Granzyme B in Mouse Splenocytes. Granzyme B was detected in immersion fixed mouse splenocytes stimulated with calcium ionomycin and PMA using Goat Anti-Mouse Granzyme B Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1865) at 15 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Background: Granzyme B
Granzyme B is a member of the granzyme family of the serine proteases found specifically in the cytotoxic granules of cytotoxic T lymphocytes (CTL) and natural killer (NK) cells (1, 2). Granzyme B plays an essential role in granule-mediated apoptosis and may have additional roles in rheumatoid arthritis and in bacterial and viral infections (3). It activates various caspases and cleaves proteins such as aggrecan (3). Mouse Granzyme B is synthesized as a precursor (247 residues) with a signal and a pro peptide (residues 1-20) and a mature chain (residues 21‑247) (4, 5). The recombinant mouse Granzyme B consisting of residues 17 to 247 was expressed and purified. After activation with cathepsin C, it cleaves a thioester substrate.
