DEFINITION

Classification: 530/816

Attached to the carrier via a bridging agent:

(under subclass 815) Cross-reference art collection wherein the peptide or protein is bonded to the polymeric carrier through an intermediate compound which attaches to both the peptide or protein and the carrier.

(1) Note. The formation of the immobilized peptide or protein may be in a stagewise manner with a reaction between the carrier and bridging agent being complete before the peptide or protein is added or in a process in which the carrier, bridging agent, and peptide or protein are present simultaneously in which case some care should be exercised in distinguishing the process of this subclass from mere entrapment. In general, if three separate entities, i.e., enzyme and two different chemical species are present simultaneously, bonding through a bridging agent should be presumed.

(2) Note. A product or process classifiable in this subclass combines a polymeric carrier with a bridging agent to provide functional groups for attachment. It should be noted that similar functional groups can be provided by formation of a polymeric carrier by copolymerization of monomers one or more of which contain the desired functional group for attachment and that such would be provided for in subclass 421.
