CD28 Antibody, anti-human, PE, REAlease®

01MT09501

Clone REAL105 is an antibody fragment derived from the full CD28 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 REAL105 recognizes the human CD28 antigen, a type I transmembrane protein, which is highly expressed on CD3+ thymocytes, most peripheral thymocytes, and plasma cells but not in less mature B cells. Binding of CD28 to its ligands CD80 or CD86 costimulates T cell effector function and T cell–dependent antibody production in vitro and in vivo.
