Background: Serpin A1/alpha 1-Antitrypsin

The human serpin superfamily consists of at least 35 members that target not only serine proteases, but also selected cysteine proteases and non-protease proteins. Serpins bind the protease active site resulting in a major conformational rearrangement that traps the enzyme in a covalent acyl-enzyme intermediate. As protease inhibitors, serpins have an array of functions including regulating blood clotting, the complement pathway, extracellular matrix remodeling, and cell motility. They are also involved in activities that extend beyond their ability to inhibit proteases. For instance, they may also regulate blood pressure, angiogenesis, or act as storage/transport proteins.

Human Serpin A1 DuoSet ELISA
By Anonymous on 10/20/2021
Sample Tested: 293T human embryonic kidney cell line

I used this kit to detect the human AAT expressed in mice and it worked like a charm. No background with the mice AAT as reported. The kit is very sensitive and the procedure is straightforward.

Human Serpin A1 DuoSet ELISA
By Anonymous on 09/28/2020
Sample Tested: Serum

Kit is very sensitive and samples had to be diluted a lot in a serial dilution.
The kit is specific for human A1AT and no cross-reactivity with mouse A1AT was observed. The kit is very reproducible.
We used Thermo Fisher's QuantaBlu substrate for detection.
