DEFINITION

Classification: 530/333

Synthesis of peptides:

(under subclass 300) Processes which a polypeptide is synthesized (1) From amino acids or protected amino acids or (2) by joining polypeptides or protected polypeptides to amino acids or protected amino acids or polypeptides or protected polypeptides.

(1) Note. Methods of protecting or removing protective groups from peptides are included here even if the synthesis steps are nominal.

(2) Note. This and the indented subclasses provide for patents which claim synthesis techniques not directed to producing one of the named peptides provided for in subclasses 301-316 above. The synthesis of a peptide is usually unique to that peptide and the search of the subclasses providing for the disclosed products of a broad synthesis process is strongly recommended.
