Abstract
Peptides or proteins are sequenced by stepwise degradation while immobilized on a glass support derivatized with a silica-binding substance bearing a free acid group, especially a sulfonic acid group. The support is preferably derivatized with 2-(4-chlorosulfonyl phenyl) ethyl trimethoxysilane. Peptide sequencing performance is improved if the support is also derivatized with a monomeric silica-binding substance bearing a free quaternary ammonium group, such as N-trimethyoxysilyl propyl -N,N,N-trimethyl ammonium chloride.
