Specifications for Granzyme A Antibody, anti-human, REAfinity™


Clone REA162 recognizes granzyme A, a member of serine protease family expressed exclusively by cytotoxic T lymphocytes and natural killer (NK) cells. Granzyme A is a homodimeric protease and is one of the five granzymes expressed by humans. Also known as granule enzymes, granzymes comprise majority of the mass of cytolytic granules in cytotoxic T lymphocytes (CTLs) and NK cells. NK cells and γδ T cells express granzymes constitutively, whereas expression in T lymphocytes is stimulation dependent. Main function attributed to granzymes is to indue apoptotic death of infected and transformed cells. Granzymes other than granzyme B, exert relatively weaker apoptotic activity. Additional reported functions of granzyme A include, to facilitate the migration of T and NK cells and induction of cytokine secretion.
Additional information: Clone REA162 displays negligible binding to Fc receptors.
