Detection of Human Granzyme A by Western Blot. Western blot shows lysates of NK-92 human natural killer lymphoma cell line. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human Granzyme A Monoclonal Antibody (Catalog # MAB2905) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for Granzyme A at approximately 28 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

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 262 amino acid (aa) precursor with a signal peptide (aa 1‑26), a propeptide (aa 27‑28) and a mature chain
(aa 29‑262) (2). After being activated by lysyl endopeptidase removal of the propeptide, Granzyme A cleaves thioester substrates. Mature human granzyme A shares 71% amino acid sequence identity with mouse granzyme A.
