DEFINITION

Classification: 435/23

Involving proteinase:

(under subclass 18) Subject matter where the material to be measured or tested contains proteinase (endopeptidase) or the agent used for the measurement or test contains a proteinase (endopeptidase).

(1) Note. Enzymes included in this subclass are trypsin, pepsin, ficin, bromelin, papain, renin.

(2) Note. Where the hydrolytic activity of an enzyme on a protein or polypeptide is unclear it should be presumed to be an endopeptidase, classifiable in subclass 23.
