Introduction
Bio-Plex Pro™ Cell Signaling Assays
Cell signaling is a complex process through which cells receive and
respond to stimuli from the surrounding environment. For example,
circulating cytokines and chemokines elicit a response from lymphocytes
by binding to cell surface receptors and activating intracellular
phosphoprotein signaling cascades. This turns on and off specific
genes in the nucleus — thus regulating protein expression, cell growth,
proliferation, motility, and survival (Chang and Karin 2001). Aberrant
signaling can lead to serious pathologies including cancer, autoimmune
diseases, cardiovascular disease, and neurological disorders.
Understanding which cell types and signaling pathways are involved in a
disease allows researchers to develop more precisely targeted therapies
with better efficacy and safety.
Bio-Plex Pro cell signaling assays are magnetic bead-based
immunoassays for the detection of intracellular phosphoproteins and
total target proteins in cell and tissue lysates. The assays are available as
singleplex sets, which researchers can combine on their own to make a
multiplex assay, or as premixed, all-in-one, multiplex kits. Phosphoprotein
detection and total target detection are carried out in separate wells of a
96-well assay plate, with just 1–10 μg of sample per well.
The assays have been optimized for exceptional sensitivity, high
specificity and improved performance over western blotting. The use
of magnetic (MagPlex) beads allows automation of wash steps on a
Bio-Plex Pro or similar wash station, which greatly simplifies assay
processing and improves assay precision.

Principle
Technology
The Bio-Plex
®
suspension array system is built upon the three core
elements of xMAP technology:
n
Fluorescently dyed microspheres (also called beads), each with a distinct
color code or spectral address to permit discrimination of individual tests
within a multiplex suspension. This allows simultaneous detection of up to
500 different types of molecules in a single well of the 96-well microplate
on the Bio-Plex
Bio-Plex

®
3D system, up to 100 different types of molecules on the

MAGPIX™system
flow cytometry–based instruments with two lasers and associated optics
to measure the different molecules bound to the surface of the beads. In
the Bio-Plex MAGPIX system, the entire sample load volume is injected into
a chamber where the beads are imaged using LED and CCD technology
n
A high-speed digital signal processor that efficiently manages the
fluorescence data
Assay Format
Bio-Plex Pro
™
assays are essentially immunoassays formatted on
magnetic beads. The assay principle is similar to that of a sandwich
ELISA (Figure 1). Capture antibodies directed against the desired
biomarker are covalently coupled to the beads. Coupled beads react
with the sample containing the biomarker of interest. After a series of
washes to remove unbound protein, a biotinylated detection antibody
is added to create a sandwich complex. The final detection complex is
formed with the addition of streptavidin-phycoerythrin (SA-PE) conjugate,
which serves as a fluorescent indicator or reporter.

Data Acquisition and Analysis
Data from the reactions are acquired using a Bio-Plex system or similar
Luminex-based reader. When a multiplex assay suspension is drawn into
the Bio-Plex 200 reader, for example, a red (635 nm) laser illuminates
the fluorescent dyes within each bead to provide bead classification
and thus assay identification. At the same time, a green (532 nm)
laser excites PE to generate a reporter signal, which is detected by a
photomultiplier tube (PMT). A high-speed digital processor manages
data output, and Bio-Plex Manager
™
software presents data as median
fluorescence intensity (MFI). The relative concentration of analyte bound
to each bead is proportional to the MFI of the reporter signal.
Using Bio-Plex Data Pro
™
software, data from multiple instrument runs
can be combined into a single project for easy data management, quick
visualization of results, and simple statistical analysis.

Detailed Instructions
The following pages provide detailed instructions for each step of the assay
procedure, including sample preparation, running the assay, and reading
the plate with Bio-Plex Manager
™
and Luminex xPONENT software.
1. Prepare the Samples
Considerations
n
The degree of phosphorylation of a given analyte is highly dependent
on the cell type and cell stimulation or treatment conditions
n
Cell lines may vary in their signaling responses to the same stimulation
n
The suggested final protein concentration range in the assay is
3–200 μg/ml (0.15–10 μg per assay well) except for Pl3K p85 (Tyr
which is 31–1,000 μg/ml (1.6–50 µg/well)
n
Optimization of cell lysate concentration may be needed based on
target protein expression levels
n
Cell lysate should be clear of particulate matter before use
Cell Lysates
The Bio-Plex Pro™ cell signaling reagent kit (catalog #171-304006M)
is required for preparing lysates derived from cell culture and tissue
samples. Just before use, prepare an adequate volume of cell lysis buffer
by adding PMSF and cell lysis factor QG.
n
Prepare 500 mM PMSF by dissolving 0.436 g PMSF in 5 ml DMSO.
(Store as aliquots at –20°C). Add PMSF to the cell lysis buffer at a final
concentration of 2 mM
n
Reconstitute cell lysis factor QG to 100x with 250 μl of diH2O and vortex
to mix. Add the reconstituted factor to the cell lysis buffer to a final 1x
working concentration

Adherent Cells
1. Stop the treatment reaction by aspirating the culture medium and
quickly rinsing the cells with ice-cold cell signaling cell wash buffer
(bottle with the blue cap). The volume of buffer required is the same
as the volume of aspirated cell culture medium. Keep the cells on ice
during all steps when possible.
2. Completely remove the buffer before lysing the cells.
3. Immediately add the cell lysis buffer to the cells. The amount of
lysing solution needed depends on the cell density in the culture
vessel (for example, add 1.5–2 ml of lysis buffer to a 10 cm dish that
is ~80% confluent).
Note: It may be necessary to lyse the samples with different volumes of
cell lysis solution to obtain the specified protein concentration range.
4. Scrape the cells with a cell scraper, collect cell suspension into an
appropriately sized tube and gently rock for 20 min at 4°C.
5. Perform either of the following to remove insoluble cellular particulates:
n
Centrifuge the cell lysate solution at 4,500 x g for 20 min at 4°C,
and then filter the lysate using a 0.45 μm syringe filter
n
If the lysate volume is not adequate for filtration, centrifuge the lysate
at 15,000 x g for 10 min at 4°C using a benchtop microcentrifuge
6. Collect the filtered lysate or supernatant after centrifugation.
7. Measure protein concentration using Bio-Rad’s DC
™
protein assay
kit and if needed, adjust protein concentration with cell lysis buffer
containing PMSF and cell lysis factor QG.
8. The suggested working protein concentration range for Bio-Plex
®
cell signaling assays is 3–200 μg/ml (0.15–10 μg per assay well).
9. Store the aliquoted lysates at –70°C until ready to use.
9
Page 12
Suspension Cells
1.
Collect cell suspension and pellet the cells by spinning at 1,000 x g for
5 min at 4°C.
2. Aspirate off cell culture medium completely.
3. Wash by resuspending the cells with ice-cold cell wash buffer
(bottle with the blue cap)
.
4. Centrifuge the cells at 1,000 x g for 5 min at 4ºC.
5. Completely remove the buffer.
6. Immediately add the proper volume of cell lysis buffer and gently rock
for 20 min at 4°C.
7. Remove insoluble cellular particulates as described in Adherent Cells
step 5 above
.
8. Follow Adherent Cells steps 6–9 above.
Tissue Samples
1. Cut the tissue into small pieces (~3 x 3 mm) for ease of handling and
blood removal. If necessary, wash the tissue with ice-cold cell wash
buffer (bottle with the blue cap) to completely remove all blood. Then
transfer the tissue to a 2 ml tissue grinder.
2. Add an adequate volume of cell lysis solution and grind the tissue
sample on ice using approximately 20 strokes.
Note: It may be necessary to lyse the samples with different volumes of
cell lysis solution to obtain the specified protein concentration range.
3. Transfer the ground tissue to a clean microcentrifuge tube and freeze
sample at –70°C. Freezing and thawing samples helps increase cell
lysis effects.
4. Thaw the sample and sonicate on ice (for example, with a Sonifier
450: Duty Cycle = 40, Output = 1, Pulse Sonicating = 18x).
5. Remove insoluble cellular matter as in Adherent Cells step 5 above.
6. Follow Adherent Cells steps 6–9 above.

2. Plan the Plate Layout
Prior to running the assay, determine the total number of wells in the
experiment using the Plate Layout Template on page 30 or the Plate
Formatting tab in Bio-Plex Manager. A suggested plate layout is shown in
Figure 2, with all conditions in duplicate. Please note that the Bio-Plex 200
instrument reads the plate vertically.
12
Page 15
1. Assign blank, negative control, positive control, and samples
accordingly.
Note: When designating blank using
B
, Bio-Plex Manager
software will automatically subtract the blank MFI value from all other
assay wells.
2. Once the total number of wells is known, see Tables 6–9 or the
Calculation Worksheet on pages 32–33 to determine the required
volumes of beads, detection antibodies, and streptavidin-PE to use.
Note that 20–25% excess volume is included in the calculations to
compensate for transfer loss.

3. Prepare the Wash Method
The cell signaling assays are compatible with both magnetic separation
and vacuum filtration methods. However, for best results, we recommend
performing the assays in a flat bottom plate with magnetic separation.
Table 4. Summary of compatible wash stations and plate types.
Wash Method Wash Station Assay Plate
Magnetic separation Bio-Plex Pro Flat bottom plate
Bio-Plex handheld magnetic washer
Vacuum filtration Vacuum manifold (manual) Filter plate
Setting up the Bio-Plex Handheld Magnetic Washer
Place an empty flat bottom plate on the magnetic washer by sliding it
under the retaining clips. Push the clips inward to secure the plate. Make
sure the plate is held securely. For detailed instructions, refer to the user
guide (bulletin 10023087).
Setting up the Bio-Plex Pro
The wash station should be primed before use. See bulletin 5826.
1. Install the appropriate plate carrier on the wash station.
2. Use the Prime procedure to prime channel 1 with wash buffer.
Note:
n
Before using the Bio-Plex Pro wash station, make sure to define/edit a
program with the correct settings for cell signaling assays (Table 5)
n

Setting up a Vacuum Manifold
Calibrate the vacuum manifold by placing a standard 96-well flat bottom
plate on the unit and adjusting the pressure to between –1 and –3" Hg. In
general, 200 μl liquid should take 5–6 sec to clear the well. For detailed
instructions, refer to bulletin 10005042.
Using a Vacuum Manifold
n
After each incubation, place the filter plate on a calibrated vacuum
apparatus and remove the liquid by vacuum filtration
n
To wash, add 200 μl wash buffer to each well and remove the liquid as
before. Ensure that all wells are exposed to the vacuum
n
Thoroughly blot the bottom of the filter plate with a clean paper towel
between each vacuum step to prevent cross contamination
n
Place the assay plate on the plastic plate holder/tray as needed
n
Before each incubation, gently cover the plate with a new sheet of
sealing tape. Avoid pressing down over the wells to prevent leaking
from the bottom

Considerations
n
Bring all assay components and samples to room temperature before use
n
Use calibrated pipets and pipet carefully, avoiding bubbles
n
Assay incubations are carried out in the dark. Cover the plate with
aluminum foil or otherwise protect from extended exposure to light
DAY 1
Prepare Samples and Controls
1. Thaw sample lysates and keep on ice (see Section 1, Prepare the
Samples, for lysate preparation).
2. Reconstitute lyophilized cell lysate control with 250 μl of diH
vortex for 5 sec to mix, and incubate at room temperature for 20 min.
Protein concentration is now 200 μg/ml. Unused lysate can be stored
at –20°C for 3 months.
3. Centrifuge all samples and lysate controls at 15,000 x g for 10 min at
4°C before dispensing to wells.
Prepare and Add Coupled Beads and Samples
4. Use Tables 6 and 7 or the Calculation Worksheet on pages 32–33
as a reference to calculate the volume of coupled beads and wash
buffer needed.
2
O,
5. Add the required volume of wash buffer to an appropriately-sized
polypropylene tube. This will be used to dilute beads to 1x.
6. Vortex the 20x stock of coupled beads at mid speed for 30 sec.
Carefully open the cap and pipet any liquid trapped in the cap back into
the tube. This is important to ensure maximum bead recovery. Do not
centrifuge the vial; doing so will cause the beads to pellet.
16
Page 19
7. Dilute coupled beads to 1x by pipetting the required volume into the
tube containing wash buffer. Vortex.
Each well of the assay requires 2.5 μl of the 20x stock adjusted to a
final volume of 50 μl in wash buffer.
Note: To minimize volume loss, use a 200–300 μl capacity pipet to
remove beads from the 20x stock tube. If necessary, perform the volume
transfer in 2 steps. Do not use a 1,000 μl capacity pipet and/or wide
bore pipet tip.
8. Protect the beads from light with aluminum foil. Equilibrate to room
temperature prior to use.
Preparing 1x coupled beads from 20x stock (includes 20% excess volume):

9. Cover unused wells of the assay plate with sealing tape.
10. Prewet the filter plate. Skip this step if using a flat bottom plate.
a. Prewet the wells with 200 μl wash buffer and remove the liquid by
vacuum filtration. Dry the bottom of the filter plate thoroughly by
blotting on a clean paper towel.
11. Vortex the diluted (1x) beads for 15 sec at medium speed. Transfer
50 µl to each well of the assay plate.
12. Wash the plate two times with 200 µl wash buffer according to your
method of choice.
17
Page 20
13. Gather the samples, Bio-Rad cell lysate controls, and blank. Use
detection antibody diluent as the blank. Transfer 50 µl of each sample
or blank to the appropriate wells of the plate.
14. Cover with a new sheet of sealing tape and incubate in the dark
overnight (15–18 hr) at room temperature with shaking.
Note: Fully resuspend the beads/sample mixture by vigorously shaking at
900–1,100 rpm for 30 sec. Slowly ramp up to speed to avoid splashing.
Then turn down to 300–450 rpm for the specified incubation time.
