Scientific Data Images for Human Granzyme B Antibody

Detection of Human Granzyme B by Western Blot.

Western blot shows lysate of NK-92 human natural killer lymphoma cell line. PVDF membrane was probed with 0.5 µg/mL of Mouse Anti-Human Granzyme B Monoclonal Antibody (Catalog # MAB2906) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for Granzyme B at approximately 32-35 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Granzyme B in Human PBMCs.

Granzyme B was detected in immersion fixed human peripheral blood mononuclear cells (PBMCs) using Mouse Anti-Human Granzyme B Monoclonal Antibody (Catalog # MAB2906) at 8 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Detection of Human Granzyme B by Simple Western^TM.

Simple Western lane view shows lysates of NK-92 human natural killer lymphoma cell line, loaded at 0.2 mg/mL. A specific band was detected for Granzyme B at approximately 42 kDa (as indicated) using 5 µg/mL of Mouse Anti-Human Granzyme B Monoclonal Antibody (Catalog # MAB2906) . This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

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). Human Granzyme B is synthesized as a precursor (247 residues) with a signal peptide (residues 1-18), a pro peptide (residues 19-20), and a mature chain (residues 21-247) (4-6). The recombinant human (rh) Granzyme B consisting of residues 19-247 was expressed and purified. After being activated by active cathepsin C, rhGranzyme B cleaves a thioester substrate described previously (3).
