Ancillary Reagent Kit Available  

DY008, DuoSet ELISA Ancillary Reagent Kit 2 -

This DuoSet ELISA Development kit contains the basic components required for the development of sandwich ELISAs to measure natural and recombinant human Serpin C1. The suggested diluent is suitable for the analysis of most cell culture supernate, serum, plasma, urine, and human milk samples. Diluents for complex matrices, such as serum, plasma, urine, and human milk, should be evaluated prior to use in this DuoSet.

Background: Serpin C1/Antithrombin-III

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.
