Data Example

Western Blot Detection  of  Granzyme B by Western  Blot. View Larger

Detection of Granzyme B by Western Blot. Western blot shows lysates of NK‑92 human natural killer lymphoma cell line and NK‑RL human natural killer lymphocytic leukemia cell line. PVDF membrane was probed with 0.5 µg/mL of Rabbit Anti-Human Granzyme B Monoclonal Antibody (Catalog # MAB29061) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for Granzyme B at approximately 34 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

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).
