Product Overview
Clone AOEF-19 is a rabbit monoclonal antibody that recognizes alpha-1-antitrypsin (gene SERPINA1) in human samples and is validated for Western blot, IHC, ICC/IF and immunoprecipitation. The predicted molecular weight is 46.7 kDa, and the supplier reports an observed band at about 47 kDa.
Alpha-1-antitrypsin (SERPINA1) is an abundant plasma serine protease inhibitor made mainly by the liver, whose main target is neutrophil elastase. By limiting elastase activity it protects lung tissue, and inherited SERPINA1 deficiency variants cause emphysema and liver disease, making it a major subject in respiratory and hepatic research.

Samples with a confirmed band (WB): human fetal kidney.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 10% SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 1:500 overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Immunogen
Synthetic peptide based on the sequence of human SERPINA1.
Reactivity Notes
The supplier lists reactivity with human. UniProt describes alpha-1-antitrypsin as secreted and also located in the endoplasmic reticulum. Tissue expression noted by UniProt (human): Ubiquitous. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
