Human B Cell Signaling Flow Cytometry Panel #31328
Product Information
Protocol
Product Description
CD45 is a pan leukocyte marker. B cells are identified by expression of CD19. Engagement of the B cell receptor (BCR) triggers the tyrosine phosphorylation of CD79A at Tyr182, which is mediated by Src family kinases. Following engagement of the BCR, Syk is recruited to phosphorylated ITAM motifs within the BCR signaling complex, which facilitates Syk activation through phosphorylation of Tyr525/526 within the kinase activation loop.
Product Usage Information
For individual product dilutions, refer to panel product datasheet or individual product pages.
Gating strategy for observing B cell receptor activation in B cell populations: Apply the same gating strategy for both untreated and treated cell populations. If a fixable viability dye was used, then first gate on viable cells. Next, gate on CD45+ immune cells. Viewing the CD45+ population, gate on singlets using appropriate scatter parameters, such as FSC-A vs. FSC-H. Observe CD19 vs. SSC-A and gate on CD19+ B cells. Observe phospho-CD79A (Tyr182) and phospho-Syk (Tyr525/526) within the CD19+ gate.
