TCR Vβ21.3 Antibodies

TCR Vβ21.3 is also called TCRBV21S3. Vβ21 is a subfamily of the T cell receptor. The Vβ21.3 is expressed by 2.2% to 3.6% of peripheral CD3+ cells in normal blood. This sequence is also referred to as TRBV11-2 (based on the IMGT gene nomenclature).


Clone: IG125 Isotype: IgG2a Mouse

The IG125 antibody recognizes the IGRb01 sequence identical to TCR BV21.3 sequence. Recognition of other sequences within this subfamily has not been found, but cannot be formally excluded.
