  • Alpha1‐antitrypsin is the most abundant circulating protease inhibitor. The severe Z deficiency allele (Glu342Lys) causes the protein to undergo a conformational transition and form ordered polymers that are retained within hepatocytes. This causes neonatal hepatitis, cirrhosis, and hepatocellular carcinoma. We have developed a conformation‐specific monoclonal antibody (2C1) that recognizes the pathological polymers formed by α1‐antitrypsin. This antibody was used to characterize the Z variant… CONTINUE READING
