WebThe chromatographic separation of proteins from small molecules on the basis of size was first described by Porath and Flodin, who called the process “gel filtration” (1). Moore … WebThe 3 Carboxypeptidase B exists in fresh frozen porcine pancreas tissue, at least in part, as an inactive zymogen. Extracts of an acetone powder, prepared by a different procedure, are low in enzyme activity. Treatment of these extracts with trypsin results in as much as a IO-fold increase in carboxypeptidase B activity.

WebSize-exclusion chromatography (SEC), also known as molecular sieve chromatography, is a chromatographic method in which molecules in solution are separated by their size, and in some cases molecular weight. It is usually applied to large molecules or macromolecular complexes such as proteins and industrial polymers.Typically, when an aqueous solution … WebPorath J, Flodin P (1959) Gel filtration: a method for desalting and group separation.
