Abstract
Abstract A novel polymeric disc, wafer or similarly shaped resin for carrying out the synthesis of peptide analogs via solid phase peptide synthesis techniques is provided. The polymeric disc or wafer of the invention may be made out of those resin materials presently used in bead form in solid phase peptide synthesis, such as, benzhydrylamine resins, Boc-aminoacyl-4-(oxymethyl)-phenyacetamidomethyl (Pam) resin, polyamide resins and chloromethyl resins. The disc or wafer of the invention should, preferably, have a thickness of 200-400 μm and may be of any suitable length or width. A process for the synthesis of peptide analogs utilizing the polymeric disc or wafer of the present invention is also disclosed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
172 words
Apparatus for a solid phase peptide synthesis of peptide analogs, comprising: a polymeric resin being insoluble and capable of permitting an attachment to it of a first amino acid in said solid phase peptide synthesis wherein said polymeric resin includes an inert support which is capable of permitting a transfer of said polymeric resin from a first reaction vessel to a second reaction vessel by means of a tongs instrument; and, reactor cell means for use in combination with said polymeric resin, said reactor cell means including a plurality of reaction vessels wherein at least one of said reaction vessels of said reactor cell means is capable of at least partially containing a plurality of said polymeric resins during said solid phase peptide synthesis, said polymeric resin being suitably shaped and sized for use in combination with said reactor cell means wherein said polymeric resin is not separately contained in a foraminous container within said reactor cell means which would be capable of inhibiting the flow of reagents to said polymeric resin.
Claim 2
Dependent Claim
172 words
Apparatus for a solid phase peptide synthesis of peptide analogs, comprising: a polymeric resin being insoluble and capable of permitting an attachment to it of a first amino acid in said solid phase peptide synthesis wherein said polymeric resin includes an inert support which is capable of permitting a transfer of said polymeric resin from a first reaction vessel to a second reaction vessel by means of a tongs instrument; and, reactor cell means for use in combination with said polymeric resin, said reactor cell means including a plurality of reaction vessels wherein at least one of said reaction vessels of said reactor cell means is capable of at least partially containing a plurality of said polymeric resins during said solid phase peptide synthesis, said polymeric resin being suitably shaped and sized for use in combination with said reactor cell means wherein said polymeric resin is not separately contained in a foraminous container within said reactor cell means which would be capable of inhibiting the flow of reagents to said polymeric resin.
