phpa partial hydrolyzed polyacrylamide pam msds in america
Polyacrylamide gel electrophoresis (PAGE) analysis can be conveniently applied to analyze the molecular weight of sulfated GAGs. Gels on which GAGs have been fractionated can be visualized with Alcian Blue with or without silver staining and the bands can be scanned and digitized. The average MW of a GAG is then calculated based on a mixture of HP-derived oligosaccharide standards prepared
Gel material acts as a "molecular sieve”. Gel is a colloid in a solid form (99% is water). It is important that the support media is electrically neutral. Different types of gels which can be used are; Agar and Agarose gel, Starch, Sephadex, Polyacrylamide gels. A porous gel acts as a sieve by retarding or, in some cases, by completely
