C07K1/1136 - CPC Classification

Classification description:

General methods for the preparation of peptides, i.e. processes for the organic chemical preparation of peptides or proteins of any length by chemical modification of precursor peptides without change of the primary structure by reversible modification of the secondary, tertiary or quarternary structure, e.g. using denaturating or stabilising agents
