Scientific Data Images for Human CD79B Antibody

Detection of CD79B antibody in Human Blood Lymphocytes antibody by Flow Cytometry.

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.
