Isolated whole CD4+ populations or isolated Tfh cells were stained with with AlexaFluor 647-conjugated anti-BTLA (BioLegend, 344520) and compared to Quantum AlexaFluor 647 MESF calibration beads (Bangs Laboratories) by flow cytometry. HVEM levels on B cells were determined by staining PBMCs from whole blood with anti-CD19-PE-Cy7 (BD Biosciences; 560911), anti-CD38-AlexaFluor 488 (BioLegend; 303511), anti-CD27-BrilliantViolet421 (BioLegend; 356417), anti-CD20-PE (BioLegend; 302305), and anti-HVEM-AlexaFluor 647 (BD Biosciences; 564411). B cell subsets were gated as follows: Activated (CD19+ CD20+ CD27+ CD38+), Memory (CD19+ CD20+ CD27+ CD38-), immature/transitional (CD19+ CD20+ CD27- CD38+), and plasmablasts (CD19+ CD20- CD27+ CD38+). HVEM intensity on each cell subset was converted to absolute protein numbers by reference to Quantum AlexaFluor 647 MESF calibration beads (Bangs Laboratories). Based on the mean HVEM expression on activated B cells of ∼35,000/cell, minimum surface density was estimated at ∼35 molecules/μm2 assuming an upper limit of ∼1000 μm2 total area.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
