Scientific Data Images for Human Serpin A8/Angiotensinogen Antibody
Detection of Human Serpin A8/Angiotensinogen by Western Blot.
Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human Serpin A8/Angiotensinogen Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3156) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for Serpin A8/Angiotensinogen at approximately 50-55 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Serpin A8/Angiotensinogen in Human Brain.
Serpin A8/Angiotensinogen was detected in immersion fixed paraffin-embedded sections of human brain (cortex) using 1.7 µg/mL Goat Anti-Human Serpin A8/Angiotensinogen Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3156) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

Detection of Human Serpin A8/Angiotensinogen by Simple WesternTM.
Simple Western lane view shows lysates of HepG2 human hepatocellular carcinoma cell line, loaded at 0.2 mg/mL. A specific band was detected for Serpin A8/Angiotensinogen at approximately 64 kDa (as indicated) using 10 µg/mL of Goat Anti-Human Serpin A8/Angiotensinogen Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3156) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.Applications for Human Serpin A8/Angiotensinogen Antibody

Background: Serpin A8/Angiotensinogen
Serpin A8 (serine proteinase inhibitor-clade A #8; also angiotensinogen/ANGT) is a secreted, 52-62 kDa glycoprotein member of the clade F-subfamily, serpin superfamily of protease inhibitors. It is expressed by neurons and hepatocytes, and undergoes extracellular cleavage by renin to create a ten amino acid (aa) peptide termed Ang/angiotensin I. This inactive peptide is further cleaved by ACE on the endothelial cell membrane to create bioactive Ang II. Ang II induces vascoconstriction and aldosterone release. Mature human angiotensinogen is 452 aa in length (aa 34-485). It contains Ang I (aa 34-43) that is cleaved to create Ang II (aa 34-41). Angiotensinogen may circulate in a 200 kDa complex with major basic protein (MBP), or as part of a larger 300 kDa complex with MBP and complement C3dg. Over aa 34-485, human serpin A8 shares 61% aa identity with mouse serpin A8.
