Product Information

Product Usage Information

Application Dilution
Western Blotting 1:1000

Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

TRBC1/TCRβ constant region 1 Antibody recognizes endogenous levels of total TRBC1/TCRβ constant region 1 protein. This antibody does not cross-react with TRBC2/TCRβ constant region 2 protein.

Species Reactivity:

Human

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human TRBC1/TCRβ constant region 1 protein. Antibodies are purified by peptide affinity chromatography.

Background

The αβ T Cell Receptor (TCR) is a heterodimer composed of an alpha chain and a beta chain expressed on the surface of T cells (1,2). It detects peptide antigen presented by major histocompatibility complex (MHC) molecules (1,2). Detection of cognate antigen leads to activation of the TCR signaling pathway through the CD3 signaling chains that associate with the TCR (1). The TCR chains are made up of a constant region and variable regions that get rearranged during T cell development in the thymus (3). There are two TCRβ constant genes, TRBC1 and TRBC2 (3). A population of normal T cells is polyclonal and contains a mix of TRBC1- and TRBC2-expressing T cells, while T cell malignancies are monoclonal and all express the same TCR which either contains TRBC1 or TRBC2 (4). Therefore, it is possible that T cell malignancies could be identified and targeted with reagents or therapies that can distinguish between TRBC1 and TRBC2 (4).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
