    Product Information

    Product Description

    This Cell Signaling Technology® antibody is conjugated to phycoerythrin (PE) fluorescent dye under optimal conditions and tested in-house for direct flow cytometric analysis in human cells. This antibody conjugate is expected to exhibit the same species cross-reactivity as the unconjugated Phospho-CD79A (Tyr210) (E8E9Z) Rabbit mAb #89660.

    Product Usage Information

    Application Dilution
    Flow Cytometry (Fixed/Permeabilized) 1:50

    Storage

    Supplied in PBS (pH 7.2), less than 0.1% sodium azide, and 2 mg/mL BSA. Store at 4°C. Do not aliquot the antibody. Protect from light. Do not freeze.

    Protocol

    Specificity / Sensitivity

    Phospho-CD79A (Tyr210) (E8E9Z) Rabbit mAb (PE Conjugate) recognizes endogenous levels of CD79A protein only when phosphorylated at Tyr210.

    Species Reactivity:

    Human

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr210 of human CD79A protein.

    Background

    Antigen receptors found on the surface of B cells contain a heterodimeric signaling component composed of CD79A and CD79B, also known as Ig α and Ig β, respectively (1,2). Presence of this receptor complex is essential for B cell development and function (3). Together these two proteins and the associated B cell receptor (BCR) initiate intracellular signaling following antigen binding (4,5). An immunoreceptor tyrosine-based activation motif (ITAM) found in the CD79A intracellular region appears to be important for its function (6). Antigen binding precedes formation of the CD79A and CD79B heterodimer and subsequent activation of receptor associated kinases (7). Research has shown that CD79A is a marker for B-lineage lymphoblastic leukemia (8). Additionally, investigators have found that mutations in the CD79A (MB1) gene are associated with abnormally low levels of functional B cell receptors in some cases of chronic B cell lymphocytic leukemia (9).
    Tyrosine 210 is an evolutionarily conserved non-ITAM tyrosine residue that lies within the cytoplasmic domain of CD79A/Ig-α. Research studies have shown that ligation of the BCR induces phosphorylation of tyrosine 210, which facilitates both the recruitment of BLNK to the BCR signaling complex and the activation of downstream Syk-dependent signaling (10,11). Collectively, these molecular events drive B cell activation and proliferation (12).
