The antibody was purified by affinity chromatography and conjugated with APC under optimal conditions. The solution is free of unconjugated APC and unconjugated antibody.
CD26, also known as DPP IV or THAM, is a 220 kD type II transmembrane homodimer. It consists of an α/β hydrolase domain and an eight-blade beta-propeller domain. After proteolysis of the membrane-bound CD26, a soluble form of DPP IV is released. CD26 is expressed on thymocytes (development dependent), T cells, B cells, NK cells, and macrophages. It is involved in T cell costimulation, endothelial cell migration and proteolysis processes.
