Background:
CD19 is a 95 kDa coreceptor, which amplifies the signaling cascade in B cells . On the B cell surface, CD19 associates with CD21, CD81 and Leu-13 to exert its function. The cytoplasmic tail of CD19 has nine conserved tyrosine residues playing critical roles in CD19 mediated function by coupling signaling molecules to the receptor . After B cell receptor or CD19 ligation, Tyr531 and Tyr500 of CD19 are progressively phosphorylated. This phosphorylation enables the coupling of PI3 kinase and Src family tyrosine kinase to CD19 and activates the PI3K and Src signaling pathways. Coligation of B cell receptor and CD19 also promotes Tyr409 phosphorylation in CD19. The phosphorylation at these sites enables its binding to Vav and mediates elevated intracellular calcium response, as well as the JNK pathway.
Alternative Name:
B-lymphocyte antigen CD19, B-lymphocyte surface antigen B4, Differentiation antigen CD19, T-cell surface antigen Leu-12, CD19
Application Dilution: WB: 1:500~1:1000
Specificity: CD19 pAb detects endogenous levels of CD19 protein.
Immunogen:
Synthetic peptide, corresponding to Human CD19.
MW: ~ 95 kDa
Swis Prot.: P15391
Purification & Purity:
The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is > 95% (by SDS-PAGE).
Format:
1 mg/ml in Phosphate buffered saline (PBS) with 0.05% sodium azide, approx. pH 7.3.
Storage:
Store at 4°C short term. Aliquot and store at -20°C long term. Avoid freeze-thaw cycles.
For research use only, not for use in diagnostic procedure.
