Anti-TCRβ antibodies, mouse

Anti-TCRβ antibodies, mouse

Clone: REA318 | Dilution: 1:50
Clone REA318 recognizes the mouse T cell receptor beta chain (TCRβ). The T cell receptor (TCR) is responsible for recognizing antigens bound to major histocompatibility complex (MHC) molecules. It is a disulfide-linked membrane-anchored heterodimeric glycoprotein normally consisting of the highly variable alpha and beta chains expressed as part of a complex with the invariant CD3 chain molecules. T cells expressing this receptor are referred to as TCRα/β T cells, though a minority of T cells express an alternate receptor, formed by variable gamma and delta chains, referred as TCRγ/δ T cells. TCRβ is expressed on TCRα/β T cells and thymocytes, NK1.1
thymocytes and NK-T cells.
Additional information: Clone REA318 displays negligible binding to Fc receptors.

REAfinity clone is tested against different known clones, in a blocking experiment, to identify whether they recognize completely overlapping (++), partially overlapping (+), or completely different epitopes (-). In a blocking experiment, cells are incubated with an excess of purified unconjugated REAfinity clone followed by staining with conjugated form of the other known clones.
