Detection of Human Serpin A1/ alpha 1‑Antitrypsin by Western Blot. Western blot shows human plasma. PVDF membrane was probed with 0.1 µg/mL of Sheep Anti-Human Serpin A1/a1-Antitrypsin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF12681) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Serpin A1/a1-Antitrypsin at approximately 60 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: Serpin A1/alpha 1-Antitrypsin

Serpin A1 is the archetypal member of the Serpin superfamily of the serine protease inhibitors (1). As one of the most abundant proteinase inhibitors in the circulation, it is synthesized in the liver and secreted into the bloodstream with the major function to protect tissues against neutrophil elastase. A severe serpin A1 deficiency leads to several clinical complications such as pulmonary emphysema, juvenile hepatitis, cirrhosis, and hepatocellular carcinoma (2). The deficiency is caused by point mutations in naturally occurring serpin A1 variants (over 70 are known). For example, the Z variant (Glu342 to Lys) forms intracellular inclusion bodies, is not secreted, and leads to a severe serpin A1 deficiency (3).
