TCR Vβ5.3 Antibodies

TCR Vβ5.3 is also called TCRBV5S3. Vβ5 is a multimembered subfamily of the T cell receptor. Vβ5.3 is expressed by 1% to 1.8% (mean 1.4%) of peripheral CD3+ cells in normal blood. This sequence is also referred to as TRBV5-5 (based on the IMGT gene nomenclature).


Clone: 3D11 Isotype: IgG1 Mouse

The 3D11 antibody recognizes the IGRb08 sequence. Vβ5.1 and Vβ5.2 (HPB51 and PL25 sequences) are not recognized. Reactivity on other members of the Vβ5 subfamily has not been found, but cannot be formally excluded.
