Anti-Mouse Serpinb1a Polyclonal Antibody

Leukocyte elastase inhibitor A (Serpinb1a) is a ~42 kDa protein. Neutrophil serine protease inhibitor that plays an essential role in the regulation of the innate immune response, inflammation and cellular homeostasis. Acts primarily to protect the cell from proteases released in the cytoplasm during stress or infection. These proteases are important in killing microbes but when released from granules, these potent enzymes also destroy host proteins and contribute to mortality. Regulates the activity of the neutrophil proteases elastase, cathepsin G, proteinase-3, chymase, chymotrypsin, and kallikrein-3. Also acts as a potent intracellular inhibitor of granzyme H.
