Epitope competition
In order to compare the epitope specificity of an antibody, the clone being used is compared with other known clones recognizing the same antigen in a competition assay.
Other clonesOverlap in epitope recognition with REA559
Cells were incubated with an excess of purified unconjugated TCR Vβ11 (REA559) antibody followed by staining with fluorochrome-conjugated antibodies of other known clones against the same marker. Based on the fluorescence signal obtained, the clones were identified as recognizing completely overlapping (++), partially overlapping (+), or completely different epitopes (-) of the marker.

Specifications for TCR Vβ11 Antibody, anti-human, REAfinity™


Clone REA559 recognizes the human Vβ11 T cell receptor (TCR Vβ11). The 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 α and β chains expressed as part of a complex with the invariant CD3 chain molecules. TCR Vβ11 is expressed on a subset of α/β T cells.
Additional information: Clone REA559 displays negligible binding to Fc receptors.
