Gene Pulser MXcell Electroporation Guide
The Gene Pulser MXcell Electroporation Guide
The Gene Pulser MXcell electroporation system is filled with features that will enable you to quickly optimize conditions for efficient deliver y of molecules into most eukaryotic cells, including mammalian cells and plant protoplasts. This guide will assist you in determining the parameters for obtaining efficient transfection of molecules into your favorite cells while maintaining high cell viability.
Transfection efficiency and cell viability
Transfection and cell viability are affected by:
n
Cell type and its physiological condition and state prior to electroporation: cells should be actively growing, healthy, and free of contamination
n
Temperature of buffer during electroporation: when using Gene Pulser® electroporation buffer, electroporation should be performed at room temperature
n
Cell density: for most experiments using the 96-well plate, we recommend using 150 µl of cells/well at a density of 1 x 106 to 2 x 106 cells/ml in Gene Pulser electroporation buffer
n
Concentration of the transfected molecule (RNA, DNA): ideally a concentration of 5–40 µg/ml should be used for plasmid DNA and 10–100 nM for siRNA (only Bio-Rad’s siLentMer™ Dicer-substrate siRNA duplexes)
n
The characteristics of the electric pulse
Electroporation protocols
Electroporation applies an electric pulse to cells to promote uptake of molecules (RNA, DNA) into the cells. The electric pulse is defined by parameters that can be programmed as protocols in the Gene Pulser MXcell. Two type of pulses can be delivered by the Gene Pulser MXcell: the exponent ial waveform which is defined by voltage,
capacitance, and resistance or the square waveform which is defined by voltage, pulse duration, and resistance.
The Gene Pulser MXcell can be programmed three ways:
n
Manually, under “Protocol Setup”
n
By creating a voltage gradient under “Gradient Protocol”
n
By using preprogrammed protocols under “Pre-Set Protocols”*
This guide will help you program the Gene Pulser MXcell whether you have prior knowledge of optimal electroporation conditions for your cells or not.

Gene Pulser MXcell Electroporation Guide
Glossary
Electroporation plate: a plate in which electroporation is performed; available in
12-, 24-, and 96-well formats
Mini protocol: a preprogrammed set of 4–6 different protocols delivered to 4–6 well sets
Parameter s: the physical constants (waveform, voltage, capacitance, duration,
resistance) that define the electric pulse
Preset protocols: a set of preprogrammed protocols designed for rapid screening of
multiple parameters that can be used as a template
Protocol/electroporation conditions: parameters defining the electric pulse
that will be delivered to specific well sets or wells on an electroporation plate
Waveform: defines the type of electric pulse delivered to the cells
n
The exponential waveform builds up a charge in a capacitor and when the charge is applied to the sample the voltage delivered decays exponentially, until the charge remaining is about 37% of the original pulse
n
The square waveform relies on a charge being applied to the cells for a set time
Well set: a set of four adjacent wells in a column on a 96-well plate; the same
electroporation conditions or protocol are applied to all the cells of a well set
Whole plate protocol: a preprogrammed set of 24 protocols delivered across
the entire plate
Abbreviations
Cgrad: capacitance gradient
D: duration of pulse

Electroporation Evaluation Methods
There are many techniques available to examine cells for transfection efficiency and cell viability. We have briefly summarized three commonly used methods. It is critical to the success of your experiment to evaluate all cells that were electroporated.
Fluorescence Microscopy for Adherent Cells
Fluorescence microscopy can be used to visualize a fluorescent signal within the cell. This method is commonly used when expressing a GFP-tagged protein.
Materials
n
PBS
n
Fixation buf fer: 2–4% formaldehyde in PBS
n
70% glycerol
Method
1. Remove the medium from the wells of the electroporation plate and wash the cells once with 500 –700 μl of PBS.
2. Add 300 μl of fixation buffer to each well and incubate at room temperature for 10 min.
3. Remove the fixative, and perform 2 washes with PBS.
4. Add 70% glycerol, and store the cells at 4°C until they are ready to be analyzed by
fluorescence microscopy using the appropriate filters.
Flow Cytometry
Flow cytometr y can be used to measure the number of cells containing a fluorescent tag, such as a fluorescent siRNA or a GFP-tagged protein.
Materials
n
Fixation buf fer: 2–4% formaldehyde in PBS
n
PBS
n
70% glycerol
Method
1. For adherent cells, add 100 μl trypsin per well to detach cells and add medium (200–300 μl) to inactivate the trypsin. For cells in suspension, skip this step.
2. Transfer the cell suspension to a 1.5 ml centrifuge tube and pellet the cells (300 RCF).
3. Remove the medium and resuspend the cells in 500 μl PBS.
4. Transfer the resuspended cells to a flow cytometer tube for analysis.
