DEFINITION

Classification: 436/518

INVOLVING AN INSOLUBLE CARRIER FOR IMMOBILIZING IMMUNOCHEMICALS:

(under the class definition) Subject matter in which an immunological test is carried out using an antigen, antibody or fragment thereof as part of an artificially produced composition or complex or compound which imparts the property of physical confinement or localization during a immunochemical analysis and the processes for preparing the same.

65, Glass Manufacturing, for processes of making glass articles, particularly

447+, for making a resin coated glass fiber; and subclass 22 for making a porous glass article which may find utility as an immobilization agent.

106, Compositions: Coating or Plastic, for protein containing coating or plastic compositions, particularly

4, 31.24, 31.53, 31.82, 31.94, 38.4, 124+, 614, 645, and indented subclasses.

156, Adhesive Bonding and Miscellaneous Chemical Manufacture,

77+, for pore forming in combination with a laminating step. 210, Liquid Purification or Separation,

sorption of components from a liquid; and subclass 615 for a process of use of a immobilized enzyme or microorganism to purify sewage.

264, Plastic and Nonmetallic Article Shaping or Treating: Processes,

41+, for significant molding processes which include the step of pore forming in situ.

424, Drug, Bio-Affecting and Body Treating Compositions, especially

400+, for coated products which may contain a protein; subclasses 94.1+ for a composition containing an enzyme or coenzyme including immobilized forms.

426, Food or Edible Material: Processes, Compositions, and Products, appropriate subclasses for edible protein compositions or products and related process involving the same.

428, Stock Material or Miscellaneous Articles,

411.1+, for a nonstructural stock material product in the form of a composite web or sheet including a layer comprising protein, and other appropriately titled subclasses, e.g., subclasses 435 and 458; and subclasses 304.4+ for a stock material in the form of a composite web or sheet embodying a component which is porous or cellular.

435, Chemistry: Molecular Biology and Microbiology,

174+, for carrier bound or immobilized enzymes or microbial cells and the preparation thereof and subclass 188 for enzyme conjugates, ligands and adducts. 514, Drug, Bio-Affecting and Body Treating Compositions,

2+, for a composition containing a protein.

521, Synthetic Resins or Natural Rubbers,

25+, for an ion exchange resin and the processes of making or regenerating them; and subclasses 50+ for cellular, or porous resinous bodies and the process of preparing them.

525, Synthetic Resins or Natural Rubbers,

54.1+, for a product or process of chemically reacting a protein or polypeptide with a synthetic resin.

530, Chemistry: Natural Resins or Derivatives; Peptides or Proteins; Lignins or Reaction Products Thereof,

300, 345 for peptides and reaction products thereof; subclasses 350 to 427 for proteins and the reaction products

thereof; and cross-reference art collections 800 through 859 for antigenic peptides or proteins, methods of immobilizing peptides or proteins, and the source materials from which peptides or proteins are isolated.

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

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

(3) Note. Reaction or ultra filtration cells, vials, or beakers which contain immunochemicals are not considered to be immobilized complexes or compositions. (4) Note. Antigens chemically or physically bonded to a water insoluble matrix, antibodies contained within a polymer or gel, antigens absorbed on a resin are examples of immobilized immunochemicals.

(5) Note. Haptens are considered to be antigens for the purpose of this subclass.

(6) Note. When a carrier is composed of more than one material, the patent is placed into the subclass which corresponds to the material to which the Ag or Ab is bound, e.g., a carrier which is a synthetic polymer-coated metal is placed in subclass 525.

(7) Note. The carrier material or the carrier material and a covalent bond forming agent impart to the immunochemical the property of physical confinement or localization during a 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.
