Abstract:
Macroporous gels with huge cavities and partition walls result from controlled microsyneresis during gelation. In this report we show that the microsyneresis process can be further controlled: it is possible to orient the partition walls of macropores by the use of an electric field throughout polymerization. Our oriented macroporous polyacrylamide gels offer a specific structure: a set of parallel channels of about 2 microm inner diameter, with polyacrylamide walls including acidic groups linked to the aggregated matter.

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.
