Stabilizer and Coagulants

Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH2CHCONH2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N,N'-methylenebisacrylamide. In the cross-linked form, the possibility of the monomer being present is reduced even further. It is highly water-absorbent, forming a soft gel when hydrated, used in such applications as polyacrylamide gel electrophoresis and in manufacturing soft contact lenses. In the straight-chain form, it is also used as a thickener and suspending agent. More recently, it has been used as a subdermal filler for aesthetic facial surgery (see Aquamid).

Cross-linked polyvinylpyrrolidone (PVP-P) can form complexes with phenols and alkaloids, thereby removing them from plant samples, which prevents modification and interference with proteins in order to more accurately determine protein content . It has also been reported that cross-linked polyvinylpyrrolidone (PVP-P) can increase enzyme activity.
