Anti-Human CD19 (4G7) Mouse IgG2a Recombinant Antibody, PBS Only

• 

  FC experiment of human PBMCs using 65562-1-MR (same clone as 65562-1-PBS)

  1x10^6 human PBMCs were surface stained with 0.25 ug Anti-Human CD19 (4G7) Mouse IgG2a Recombinant Antibody (65562-1-MR, Clone: 4G7) or Mouse IgG2a Isotype Control (C1.18.4) (65208-1-Ig, Clone: C1.18.4) and PE-conjugated Goat Anti-Mouse IgG. Cells were co-stained with APC Anti-Human CD3 (OKT3) Mouse IgG2a Recombinant Antibody (APC-65569, Clone: OKT3). Cells were not fixed. Lymphocytes were gated. This data was developed using the same antibody clone with 65562-1-PBS in a different storage buffer formulation.

Background Information

CD19 is a 95 kDa type I transmembrane glycoprotein belonging to the immunoglobulin superfamily (PMID: 2472450). It is expressed by B cells and follicular dendritic cells. CD19 is up-regulated at the step of B-lineage commitment during the differentiation of the hematopoietic stem cell, it remains on during subsequent stages of differentiation until finally down-regulated during terminal differentiation into plasma cells (PMID: 8528044). CD19 is involved in B cell development, activation and differentiation. It is the dominant component for the signaling complex on B cells that includes CD21 (CR2), CD81 (TAPA-1) and CD225 and acts as a critical co-receptor for BCR signal transduction (PMID: 23210908).
