DEFINITION

Classification: 530/810

CARRIER BOUND OR IMMOBILIZED PEPTIDE OR PROTEIN, PREPARATION THEREOF, E.G., USE OF BIOLOGICAL CELL FRAGMENTS AS CARRIER, ETC.:

(under the class definition) Cross-reference art collection which is an artificially produced composition or complex or compound containing the property of physical confinement or localization during a continuous chemical process or the property of enhanced recoverability in a batch process for repeated future use and processes for preparing the same.

(1) Note. Immobilization results from covalent bonding between the peptide or protein and the carrier or an ionic bonding between the peptide or protein and a carrier or sorption of a peptide or protein with a carrier, or entrapment of a peptide or protein within a carrier.

(2) Note. A carrier material may be either water soluble or water insoluble.

(3) Note. Peptides chemically or physically bonded to a

water-insoluble.

(3) Note. Peptides chemically or physically bonded to a water-soluble matrix, contained within a polymer or gel, absorbed on a resin are examples of immobilized peptides.

(4) Note. When a carrier is composed of more than one material, the patent is placed in the subclass which corresponds to the material to which the peptide is bound, e.g., a carrier which is a synthetic polymer coated metal is placed in subclass 421.

(5) Note. The carrier material or the carrier material and a covalent bond forming agent impart to the peptide or protein the property of physical confinement for localization during continuous process or the property of enhanced recoverability in a batch process which it did not possess prior to treatment with the carrier material or carrier material and a covalent bonding agent. (6) Note. Synthetic Resins vs. Polypeptides. The conceptual difference between the subject matter of synthetic resins provided for in the 520 series and polypeptides (including proteins) provided for in Class 530 is that the compounds of the 520 series have statistically distributed amino acids or blocks of amino acids in their molecules in a random sequence whereas 530 provides for molecules composed of a specific sequence of amino acids of defined identity and order (i.e., primary structure) having identity or close relation to a humerial or cellular polypeptide or having some humerial or cellular effect due to its order structure.
