摘要: The invention provides a method and reagent for the modification of polypeptides useful in experimental research in the area of genetic engineering starting from a polypeptide such as hCCK-33 in an unsulfated form which contains Tyr and Ser and/or Thr residues by first protecting the amino-groups in the starting polypeptide, masking the OH-groups in the Ser and/or Thr residues and selectively sulfating the OH-groups in the Tyr residues after deprotection.
