Product Information

Product Usage Information

This product is the carrier free version of product #96024. All data were generated using the same antibody clone in the standard formulation which contains BSA and glycerol.

This formulation is ideal for use with technologies requiring specialized or custom antibody labeling, including fluorophores, metals, lanthanides, and oligonucleotides. It is not recommended for ChIP, ChIP-seq, CUT&RUN, or CUT&Tag assays. If you require a carrier-free formulation for chromatin profiling, please contact us. Optimal dilutions/concentrations should be determined by the end user.

Formulation

Supplied in 1X PBS, BSA and Azide Free.

For standard formulation of this product see product #96024.

Storage

Store at -20°C. This product will freeze at -20°C so it is recommended to aliquot into single-use vials to avoid multiple freeze/thaw cycles. A slight precipitate may be present and can be dissolved by gently vortexing. This will not interfere with antibody performance.

Specificity / Sensitivity

CD79B (D7V2F) Rabbit mAb (BSA and Azide Free) recognizes endogenous levels of total CD79B protein. This antibody is predicted to detect multiple isoforms of CD79B.

Species Reactivity:

Human, Mouse

Species predicted to react based on 100% sequence homology

Rat, Hamster, Bovine, Pig

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Val222 of human CD79B protein.

Background

The B cell antigen receptor (BCR) is composed of membrane immunoglobulin molecules non-covalently associated with the heterodimeric signaling component, CD79A and CD79B (also known as Igα and Igβ, respectively) (1,2). The presence of this receptor complex is essential for B cell development and function (3). Following antigen binding, CD79A/CD79B heterodimers are phosphorylated and initiate intracellular signaling through Src family kinases, Lyn, Blk, and Fyn, as well as Syk and Btk tyrosine kinases (4,5). The complexity of BCR signaling results in a variety of distinct cellular functions, such as proliferation, tolerance, apoptosis, and differentiation (6). BCR-antigen ligation also leads to internalization of the complex, trafficking to late endosomes, and antigen presentation in major histocompatibility molecules on the B cell surface (7,8). CD79B enhances the phosphorylation of CD79A (9). Alternatively spliced transcript variants encoding different isoforms of CD79B have been identified (10). CD79B is widely expressed on B cell malignancies and may serve as a target for therapeutic intervention (11,12).
