Abstract:
Experimentation at the Lethbridge Research Center in Alberta, Canada using cross-polarized transmitted light to photographically record a staining technique on zymograms has proved to be successful with both color and black and white films. It has been possible to obtain the desired visible contrast without compromising the intensity of the enzyme activity bands. Increasing numbers of such PAGE gels are being submitted for photographic recording when it is believed that the image will be used for records, publication, scientific posters or AV presentations.

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.
