Appeal No. 2000-1779 Application No. 08/473,204 THE AMPA CLASS OF GLUTAMATE RECEPTORS I. The GLUR1 Subclass: Appeal No. 1997-3377 Application No. 08/216,326 Claims 31, 34 and 39 are illustrative of the subject matter on appeal and are reproduced below: 31. A method of assaying a test ligand for the ability to bind to a human CNS receptor, said method comprising the steps of: (a) incubating said test ligand with: (i) a genetically engineered cell that produces an AMPA- binding human receptor GluR1B having the amino acid sequence of residues 1-888 of SEQ ID NO:2, said cell having incorporated expressibly therein a heterologous DNA molecule encoding the human GluR1B, said cell further comprising a membrane, wherein said membrane comprises said human GluR1B, or (ii) a membrane preparation comprising human GluR1B derived from said cell, wherein said incubation is performed under conditions which permit binding of said test ligand with said human GluR1B; and (b) determining the extent of binding between said test ligand and said human GluR1B. 34. The method of claim 33, wherein said test ligand is incubated with said membrane preparation derived from said human GluR1B- producing cell. 39. The method of claim 31, wherein said cell comprises a 3.2 kilobase EcoR1/EcoR1 fragment of the plasmid pBS/human GluR1B (ATCC 75246). GROUNDS OF REJECTION Claims 31, 33, 34 and 37-40 are rejected under 35 U.S.C. § 103 over Puckett in view of Cutting. We reverse.
