PA007502.h1Fs: Recombinant Anti-mouse GITR Monoclonal Antibody (Clone: DTA-1) for Flow Cytometry, Human IgG1 Fc Silent Kappa

The rat anti-mouse GITR monoclonal antibody DTA-1 (rat IgG2b lambda) reacts with the mouse GITR protein (Glucocorticoid-Induced TNFR-Related protein or tumor necrosis factor receptor (TNFR) superfamily 18, TNFRSF 18). The DTA-1 monoclonal antibody reacts with the mouse GITR which is expressed predominantly by CD4+CD25+ T regulatory cells (Treg) and by CD25+ CD4+ CD8- thymocytes.
Our recombinant DTA-1 antibodies have a part (variable regions) or complete amino acid sequences of the rat anti-mouse GITR monoclonal antibody (hybridoma clone name or number: DTA-1).
