  • Patent number: 5362852
    Abstract: A process is disclosed for site-directed chemical modification of peptides and proteins that consists of two steps; (a) selective oxidation of a 2-hydroxyethylamine moiety, --CH(NH.sub.2)--CH(OH)--, in the peptide or protein to generate an aidehyde, and (b) reaction of the new aldehyde with a second reagent to form a product in which the native biological properties of the peptide are augmented by new and useful properties conferred by the second reagent.
