The antibody was purified by affinity chromatography, and conjugated with PE under optimal conditions. The solution is free of unconjugated PE and unconjugated antibody.
Tim-2 is a transmembrane protein known as T cell immunoglobulin and mucin domain containing protein-2. It is expressed on activated T cells and preferentially on differentiated Th2 cells. Sema4A is the ligand of Tim-2. A blockade of Tim-2/Tim-2 ligand interaction results in T cell hyperproliferation and Th2 cytokine production. Tim-2 plays a critical role in the development of atopic disease and other Th2-biased immune responses.
