  7. Elements of Data Analysis • Compensation – electronic adjustment for spectral overlap • When to compensate • Acquisition – if gating on #CD3+, requires compensation • Off-line • Spillover • Biexponential Transformation • Gates • Analysis Regions • Backgating – used to tweak gates and analysis regions so as to optimize response (maximize positive and minimize negative responses) • Training

  8. Elements of Data Analysis • Compensation – electronic adjustment for spectral overlap • When to compensate • Acquisition – if gating on #CD3+, requires compensation • Off-line • Spillover • Biexponential Transformation • Gates • Analysis Regions • Backgating – used to tweak gates and analysis regions so as to optimize response (maximize positive and minimize negative responses) • Training

  9. C (3.1%) B (3.4%) J (4.8%) A (6.8%) K (9.4%) D (10.2%) H (10.2%) F (10.5%) G (16.9%) I (12.7%) E (13.4%) • Here labs are listed in order of their total TNFa response. It is visually apparent that, while all labs had overcompensation, it is worst in labs with the lowest cytokine responses.

  10. JO Analysis Modified comp FlowJo A700-PCPCy5.5 = 6 & PCPCy5.5-PEA610 = 235 JO Analysis Autocomp FlowJo A700-PCPCy5.5 = 29.32 JO Analysis Modified comp FlowJo A700-PCPCy5.5 = 6 Inaccurate Automated Compensation:Requirement for Manual Adjustment HM analysis Diva (Lab J) CD28 PCP-Cy5.5 CD3 A700 Note: Green laser excitation for both PerCPCy5.5 & PEA610

  11. Compensation: Inspect and Manually Correct as Needed Auto Manually adjusted PE-PEA610 = 12.87 PE-PEA610 = 11

  12. EQAPOL: example of compensation affecting cytokine results

  13. Comp Profile

  14. “Corrected” Matrix (Auto-comp w/ Manual tweaking) Original vs Manually-tweaked FlowJo Compensation Values Original Matrix (Auto-comp) Note 1: Compensation pairs discussed during the call are marked with pink arrows. Red arrows indicate other compensation pairs I felt could benefit from manually tweaking compensation values. Note 2: flowjo automatically flags manual edits using red text; all other differences are flowjo doing weird rounding/display stuff (ex. for PEA610-PE “590” is really “59.36;” the value has not been modified… this drives me NUTS!
