Protein binding of procyanidins: studies using polyacrylamide gel electrophoresis and French maritime pine bark
1Department of Molecular and Cell Biology, University of California, Berkeley, California 94720-3200, USA.
Abstract:
The application of PAGE to determine the interaction between procyanidins and proteins, as presented here, enables one to directly determine the binding of either a pure of a complex mixture of flavonoids to a particular protein. If the protein of interest is an enzyme, the combination of PAGE with quantitative activity measurements allows identifying whether a change in the enzyme activity is related to the binding. Data presented suggest that PBE and EGb 761 have protein-binding properties, which, in addition to their redox-based effects, could provide a biochemical basis for their action in biological systems.

01:27SDS-PAGE
A variation of gel electrophoresis, termed polyacrylamide gel electrophoresis (PAGE), is commonly used for separating proteins according to their molecular size by passing them through a polyacrylamide gel. Because of the varying charges associated with amino acid side chains, PAGE can be used to separate intact proteins...

The first dimension separation uses the isoelectric focusing or IEF technique performed on immobilized pH gradient (IPG) strips that separate proteins according to their isoelectric points.
