Abstract

See full text

The present invention relates to a method, composition and a kit for isoelectric focusing. More closely, the present invention involves the use of to modified carrier ampholytes which are easy to separate from the proteins/peptides following finished focusing. The modification is that the carrier ampholytes are derivatised with handles interacting with a solid phase/matrix which makes them easy to remove and separate from the peptides after finished focusing. In this way, there is very little or no background from carrier ampholytes in the following MS-spectra.
