Abstract: A polyamide resin for use in peptide and protein synthesis, and a method of preparing and using same. The polyamide resin is prepared by mixing a dimethylacrylamide monomer with an N-acrylyl-diaminoalkane functional monomer in an aqueous solution together with a cross-linker and emulsifying the aqueous solution in an organic solvent. An initiator and a promoter are added to polymerize the N-acrylyl-diaminoalkane functional monomer, dimethylacrylamide monomer, and cross-linker in the form of beads. The pH of the mixture is controlled during the polymerization. The beads are used as a solid phase for peptide and protein synthesis according to methods known in the art. The conjugate of the polyamide resin and the synthesized peptide or protein is used directly for immunoassays or immunization without the need for separation of the peptide or protein from the resin and subsequent purification.

Abstract: Composition and method for detection of and vaccination against the viral causative agents of AIDS and ARC. The composition is a synthetic peptide, the amino acid sequence of which is sufficiently homologous to the amino acid sequence of the gp 41 and gp 120 subunits of the gp 160 envelope glycoprotein of HTLV-III, LAV or ARC to produce an immunogenic response in a patient and which has a hydrophilic region therein. The composition may be conjugated to an appropriate carrier for use as a vaccine against AIDS and ARC or bound to the ligand of a specific binding pair, contacted with a sample of biological fluid from a patient suspected of having contracted AIDS or ARC and thereafter contacted with the anti-ligand of the specific binding pair for detection of any antibodies against the viral causative agents of AIDS or ARC which may be present in the sample.
