Intracellular Staining by Flow Cytometry
|Detection of Granzyme A in CD56+ Human Blood Cells by Flow Cytometry. CD56+ human whole blood cells were stained with Mouse Anti-Human Granzyme A PE‑conjugated Monoclonal Antibody (Catalog # IC29051P, filled histogram) or isotype control antibody (Catalog # IC0041P, open histogram). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (Catalog # FC004) and permeabilized with Flow Cytometry Permeabilization/Wash Buffer I (Catalog # FC005).

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.
