Source / Purification
Monoclonal antibody is produced by immunizing animals with human SERPINB9 recombinant protein and reacts with an epitope surrounding Phe70.
Background
SERPINB9 (Sb9, PI-9) is a member of the serpin superfamily of proteins which bind to and inactivate serine proteinases (1,2). SERPINB9 is present in human CD4+ T cells, CD8+ T cells, NK cells, B cells, and myeloid cells, and is a physiological inhibitor of Granzyme B (GrB) (1,3,4). Granzyme B triggers apoptosis when released by cytotoxic T lymphocytes (1-4). SERPINB9 may function to protect effector and bystander cells from Granzyme B during an immune response (4). In mice, SPI6 is thought to be the functional homolog of SERPINB9 due to its inhibition of murine Granzyme B (2,5). SERPINB9 was recently identified as a potential immunotherapy target, due to its role in tumor cell survival through evasion of apoptosis (6).
Species Reactivity
Species reactivity is determined by testing in at least one approved application (e.g., western blot).
