DEFINITION

Classification: 530/334

Polymer supported synthesis, e.g., solid phase synthesis, merrifield synthesis, etc.:

(under subclass 333) Processes in which synthesis includes the use of a soluble or insoluble polymer or resin covalently attached to an amino acid residue of the polypeptide chain

being synthesized.

(1) Note. This subclass includes: (a) processes of attachment of the initial amino acid or peptide to the polymer and processes of cleavage of the polypeptide product from the polymer support; (b) processes of stepwise assembly of a polypeptide in which amino acid residues are added one at a time to the polymer supported amino acid residues or peptide; (c) processes in which a polypeptide segment is added to a polymer supported polypeptide.

(2) Note. Caution. Many patents directed to polymer supported synthesis absent a step of cleavage of the final product are originally classified in Class 525 as an after treated polymer. A complete search for polymer supported synthesis must include this class.
