Granzyme A was detected in immersion fixed human peripheral blood mononuclear cells (PBMCs) using 8 µg/mL Mouse Anti-Human Granzyme A Monoclonal Antibody (Catalog # MAB29051) for 3 hours at room temperature. Cells were stained with the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained (green).

Background: Granzyme A

Granzyme A 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. Granzyme A is the most abundant protease in CTL and NK cells. It induces caspase‑independent cell death when introduced into target cells by perforin (1). Human granzyme A is synthesized as a precursor (262 residues) with a signal peptide (residues 1‑26), a propeptide (residues 27‑28) and a mature chain (residues 29‑262) (2). The purified recombinant human Granzyme A consists of residues 26 to 262. After being activated by lysyl endopeptidase, it cleaves a thioester substrate.
