Scientific Data Images for Human Granzyme B Antibody
Human Granzyme B ELISA Standard Curve.
Recombinant Human Granzyme B protein was serially diluted 2-fold and captured by Human Anti-Human Granzyme B Monoclonal Antibody (MAB105409) coated on a Clear Polystyrene Microplate (DY990). Rabbit Anti-Human Granzyme B Monoclonal Antibody (Catalog # MAB105408) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (DY998) followed by Substrate Solution (DY999) and stopping the enzymatic reaction with Stop Solution (DY994).
Detection of Human Granzyme B by Western Blot.
Western blot shows lysates of NK-92 human natural killer lymphoma cell line. PVDF membrane was probed with 0.1 µg/mL of Rabbit Anti-Human Granzyme B Monoclonal Antibody (Catalog # MAB105408) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (HAF008). A specific band was detected for Granzyme B at approximately 34 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.Applications for Human Granzyme B Antibody
Application
Recommended Usage
ELISA
This antibody functions as an ELISA detection antibody when paired with Human Anti-Human Granzyme B Monoclonal Antibody (Catalog # MAB105409).
This product is intended for assay development on various assay platforms requiring antibody pairs. We recommend the Human Granzyme B DuoSet ELISA Kit (Catalog # DY2906-05) for convenient development of a sandwich ELISA or the Human Granzyme B Quantikine ELISA Kit (Catalog # DGZB00) for a complete optimized ELISA.

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).
