Anti-CD19 (human), Unconjugated Clone B-C3 [Mouse]

Specificity: Recognises a 95 kDa protein, Format: Phosphate-buffered saline with 1 % BSA and 0.1 % sodium azide, Working Dilution: Use 10 µl to label 106 cells or 100 µl of whole blood, Storage: Stable at +2-8°C for 12 months. For longer storage freeze aliquots, Application Notes: Suitable for Flow Cytometry Protein function: Functions as coreceptor for the B-cell antigen receptor complex (BCR) on B-lymphocytes. Decreases the threshold for activation of downstream signaling pathways and for triggering B-cell responses to antigens (PubMed:2463100, PubMed:1373518, PubMed:16672701). Activates signaling pathways that lead to the activation of phosphatidylinositol 3-kinase and the mobilization of intracellular Ca(2+) stores (PubMed:9382888, PubMed:9317126, PubMed:12387743, PubMed:16672701). Is not required for early steps during B cell differentiation in the blood marrow (PubMed:9317126). Required for normal differentiation of B-1 cells. Required for normal B cell differentiation and proliferation in response to antigen challenges (PubMed:2463100, PubMed:1373518). Required for normal levels of serum immunoglobulins, and for production of high-affinity antibodies in response to antigen challenge (PubMed:9317126, PubMed:12387743, PubMed:16672701).
