Introduction: PlasmaDive Mini Assay Panel at a Glance
Blood is the most frequently used biological sample in clinical research and routine laboratory diagnostics. Levels of blood proteins reflect the health status of single organs and the body as a whole. Changes in composition of proteins in the blood can be correlated to disease onset or therapy response. Often the relative changes in protein concentrations to each other are the key indicator of a certain condition. Only monitoring the levels of major blood proteins simultaneously makes possible to recognize the “Big Picture” and explain pathological processes going on in the body.
The PlasmaDiveMini Assay Panel was designed for targeted proteomics approaches - Multiple Reaction Monitoring (MRM, also called SRM) or Parallel Reaction Monitoring (PRM) - which focus on quantifying predefined sets of proteins with high sensitivity and reproducibility. Biognosys is unique in its ability to perform scheduled highly multiplexed MRM and PRM measurements based on its innovative iRT concept and its specifically developed signal processing software – SpectroDive™. Both, iRT and SpectroDive™, are integral parts of Biognosys’ Assay Panels.
The PlasmaDiveMini Assay Panel optimally combines 100 peptide MRM or PRM assays in one scheduled multiplexed method. Each peptide is representative of a human plasma protein (Table 1). The PlasmaDiveMini workflow requires as little as 10 µl of plasma and 48 hours to provide actionable clinically-relevant data.

Note 14
We recommend to use a resolution of 17.5k (Orbitrap) or 30k (Orbitrap HF) which corresponds to a max fill time of 55ms per precursor, due to the high level of multiplexing of the assay panel.

The Qvalue indicates the confidence of the endogenous (light) peptide identification (lower Qvalue indicates higher confidence) (Note 15).
95.2. The bottom right panel shows the sum of all transitions together with the peak boundaries as well as quantitative information about this peptide.
95.3. You can zoom in the plots and perform various actions by right clicking on the plot. Right clicking also enables you to set the scale back to default after zooming.
95.4. You can select from various plots to be displayed in the pull-down menus on top for ‘Upper panel’ and ‘Lower
panel’ e.g. to ‘Alignment view’ in order to review one
peptide across all runs.
96. Review the peptide signals (User Verification).
96.1. When a peptide is selected, you can manually accept or reject it. Use the menu that appears by right clicking on the peptide node or toggle using the keyboard hotkeys “A and R. If no action is performed, the peptides remain in the analysis as unchecked (no user verification).
96.2. To manually change peak integration, readjust the green integration boundaries (green box). Drag and drop the border to the correct location. The status of the peak will change to User Manually Integrated.
96.3. To return to the SpectroDive initial integration, right click on the respective peptide node and select ‘Remove User Peak’.
96.4. You may make a comment to each peptide by right
clicking on the peptide node and selecting ‘Comment (C)
(Note 16).
97. Peptide node includes the transition group node. Transition group nodes are used to group transitions according to isotopic labelling. If you select the transition group node on the left you will again see two graphical panels on the right. The top panel shows the transitions of this transition group in different colours. The bottom panel displays information about the peak. You can see quantitative as well as chromatographic information.
98. One level below you can find the transition node. If transition node is selected you will see again two graphical panels on the left that show the information specific to this transition.
99. You can use multiple filtering options at the bottom of the left panel to select specific nodes of the tree (e.g. in Qvalue filter
when ‘Value’ is set ≤ 0.01, only the peptides with Qvalues ≤0.01 are displayed).

Troubleshooting Guide
This troubleshooting guide may be helpful in solving issues that may arise.
Issue
Possible Cause
Recommended Solution
LC column is clogged during sample analysis
Solid particles were not completely removed from the samples during the centrifugation (step
44)
Transfer final samples to single vials and repeat a cold centrifugation (4°C) as described in step 44.
The first iRT peptide behaves irregularly
LC gradient starts with > 1% AcN
Ensure you use the LC settings as recommended in Section E. Because of the high peptide hydrophilicity slight irregularities of the first iRT peptide behaviour still can be observed. This usually does not influence the quality of calibration.
iRT calibration is not linear
Non-linear gradient was used
Use linear gradient and LC settings as recommended in the Section E.
A minor issue in chromatographic system if there are only 1 or 2 outliers from linearity
Check manually if respective iRT peaks are correctly integrated and if the peak shapes are satisfactory. If not, exclude outliers from calibration by clicking on
“Edit…” in ‘2) Choose LC
calibration’ section.

Issue
Possible Cause
Recommended Solution
A major defect in chromatographic system if iRT calibration is not linear through the whole range
Please contact the technical support of the LC manufacturer.
No signal on LC-MS when analyzing samples
Problem with sample preparation
Prepare and analyze a control sample with Reference Peptide Mix diluted in LC Buffer (keep the dilution rate as in the Section E of the protocol). If you see a signal on LC-MS your initial samples were not prepared correctly.
Problem with the LC-MS system
If you don’t see any signal on
your LC-MS after analyzing the control sample from above please contact the technical support of your LC­MS vendor.
SpectroDive cannot load runs from my Thermo Scientific instrument
The Thermo API might not be properly registered
Contact Thermo Scientific to download the newest version of the msFileReader API. Run the installer in administrator mode.
An error “iRT calibration failed” appears when
loading my runs into SpectroDive
The Reference Peptide Mix was not spiked into samples before LC-MS analysis
Check the raw files in the XCalibur software for iRT peptides and if they are not visible re-analyze the samples by spiking-in the Reference Peptide Mix according to the protocol. Further details on the iRT peptides can be found at
www.biognosys.com/shop/irt­kit
The raw files are corrupted
Transfer the raw files from the instrument again.
SpectroDive did not analyze my runs, I only see grey run names in the analysis tree
The Reference Peptide Mix was not spiked into samples as per protocol before LC-MS analysis
Spike the Reference Peptide Mix into the samples (Section E) and repeat the analysis.

Issue
Possible Cause
Recommended Solution
Only iRT peptides are displayed in SpectroDive analysis tree
The corresponding Panel Plug-in is not correct or not installed
Install the correct Panel Plug-in for the kit you are using.
Analytical run was performed with incomplete transition list (e.g. without transitions for panel peptides)
Check if the transition list contains panel peptides. If not, do the calibration according to the protocol (Section F) and re-analyze the samples with the corrected MS-method.
Exported report is empty or does not correspond to the description in the manual
A correct SpectroDive Panel Plug-in is missing
Install a correct Panel Plug-in for the kit you are using.
The incorrect report schema was chosen in step 101 when generating the report
Choose the correct report schema and export the report again.
Some of the protein quantities in my report are shown as "Not Detectable"
Low quality of the analytical run (unsatisfactory LC-MS performance)
Control performance of your LC-MS system and repeat the sample analysis.
The protein concentrations are below the limit of quantification
Detectability of target proteins may vary between samples as some of the proteins are only detectable in certain medical conditions.
