Data Examples
Detection of CD79B in Human Blood Lymphocytes by Flow Cytometry. Human peripheral blood lymphocytes were stained with Human CD79B Monoclonal Antibody (Catalog # MAB6620) followed by Allophycocyanin-conjugated Anti-Mouse IgM Secondary Antibody (Catalog # F0117) and Human CD19 PE-conjugated Monoclonal Antibody (Catalog # FAB4867P). Quadrant markers were set based on normal mouse IgM control antibody staining.

Background: CD79B
CD79B, also known as Igb and B29, is a 36 kDa transmembrane glycoprotein in the immunoglobulin superfamily. It contains a single Ig‑like domain in its extracellular region (ECD) and one cytoplasmic immunoreceptor tyrosine-based activation motif (ITAM). Alternate splicing generates a short isoform that lacks nearly the entire Ig‑like domain. Heterodimers of CD79A/Iga and CD79B associate with a membrane bound immunoglobulin on the B cell surface to form the B cell antigen receptor complex (BCR). CD79A and CD79B are required for BCR-mediated signaling and consequently for the development and activation of B lineage cells. Within the ECD (aa 29-159), human CD79B shares 54% aa sequence identity with mouse CD79B.
