DEFINITION

Classification: 530/412

Separation or purification:

(under subclass 350) Processes in which a protein is separated from another material.

(1) Note. This and the indented subclasses provide for original patents directed to the production of proteins claimed generically and for cross-references of named proteins provided for above.

(2) Note. This and the indented subclasses provide for a process which includes a chemical reaction so long as the chemical reaction is part of a separation or purification procedure and provided that the reactants do not include the protein to be recovered.

(3) Note. See subclass 344 for a comprehensive listing of classes which provide for separation process where the material purified is not specifically claimed as being a protein.
