the epoxy groups in eehpa-modified proteins have a great many potential uses : disaggregation of supramolecular structures , conversion of hydrophobic membrane proteins or tryptic peptides into water-soluble coloured proteins or peptides , inhibition of tryptic cleavage at lysine residues , synthesis of chemically reactive proteins or enzymes for affinity chromatography or immobilized-enzyme technology , two-dimensional separation techniques for complex protein mixtures , detection of specific protein-binding sites for organic substrates or tumour diagnostics , synthesis of defined artificial glycoproteins for biophysical and cytochemical studies and chemical synthesis of radioactively labelled proteins .
