Specifications for CD127 Antibody, anti-human,


Clone REAL102 is an antibody fragment derived from the full CD127 antibody molecule. It displays no binding to Fc receptors. The recombinantly engineered antibody fragments are multimerized to form the REAlease Complex to bind markers with high avidity.
Clone REAL102 recognizes the CD127 antigen, which is the α-chain of the interleukin 7 (IL-7) receptor, a type I membrane glycoprotein. Signaling of IL-7 through the IL-7R requires both IL-7Rα and the common cytokine gamma chain (γc). CD127 can be identified on immature B cells through the early pre–B stage, on thymocytes, and on most mature T cells with transient down-regulation upon activation. On regulatory T cells CD127 is absent and its expression is inversely correlated with FoxP3 expression and suppressive function. CD127 is also used by thymic stromal derived lymphopoietin (TSLP) as part of a complex.
The REAlease Kits consist of the respective fluorochrome-conjugated REAlease Complexes and the REAlease Support Kit for removal of the REAlease Complexes and optional relabeling with different fluorochrome-conjugated REAlease Complexes.
