title: Sequence homology analysis of proteins by chemical cleavages: using a mono and two dimensional sodium dodecyl sulfate-polyacrylamide gel electrophoresis.
abstract: The examination of possible sequence homology in proteins using SDS-PAGE systems after chemical cleavage is described. After SDS-PAGE, the establishment of amino acid compositions, the techniques of staining gel and five different methods of chemical cleavages (cyanogen bromide, BNPS-skatole, hydroxylamine, formic acid and nitrothiocyano benzoic acid) have been used for peptide mapping studies. Potential applications of this technique are discussed from both the biochemical and immunochemical point of view.
