Purified human α-1-antitrypsin

General description

α-1-antitrypsin belongs to the serpin family and is a strong serine protease inhibitor. Its pivotal role is to protect lower respiratory tract against proteolytic destruction by human leukocyte elastase. Mutation in AAT gene will reduce the serum concentration of α-1-antitrypsin and hence increase the risk of emphysema. Anti-α1-antitrypsin antibody (diluted 1:9000) can be used as a capture antibody for determination of transgene expressions levels. It can also be used in immunoelectrophoresis. Rabbit anti-α1-antitrypsin antibody reacts specifically with α1-antitrypsin of human.

Physical form

Lyophilized from 0.01 M phosphate buffered saline, pH 7.2.


Anti-α1-antitrypsin antibody (diluted 1: 1000) can be used in ELISA. It can also be used for probing immunoblots to identify A1AT. Additionally, it can be used in Ouchterlony double diffusion.

Rabbit anti-α1-antitrypsin antibody can also be used in immunoelectrophoretic techniques.
