Properties of Polyacrylamides polymerdatabase

Polyacylamides are high molecular weight water soluble or swellable polymers formed from acrylamide or its derivatives. Their glass transition temperature is well above room temperature (> 400 K). The only commercially important polyacrylamide is poly (2-propenamide) which is simply called polyacrylamide or PAM [-CH 2 CH (CONH 2 )-].

There are three main advantages of gradient gels over linear gels: 1.The advancing edge of the migrating protein zone is retarded more than the trailing edge, thus resulting in a sharpening of the protein bands.2.The gradient in pore size increases the range of molecular weights that can be fractionated in a single gel run.3.Proteins with close
