Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
114 words
The method which comprises: (1) resolving a mixture of proteins or peptides by gel electrophoresis; (2) transferring a sample peptide or protein isolated on said gel to a hydrophobic synthetic resin membrane of open porous structure upon which said sample is adsorbed; (3) staining said sample adsorbed on said membrane; (4) dividing the membrane into strips bearing portions of the stained sample; (5) placing at least one of said strips into a cylindrical sequenator reaction chamber the longitudinal axis of at least one of said strips being substantially parallel to the longitudinal axis of said cylindrical reaction chamber; (6) placing the reaction chamber in a sequenator; and (7) subjecting the sample to sequence analysis.
Claim 2
Independent Claim
114 words
The method which comprises: (1) resolving a mixture of proteins or peptides by gel electrophoresis; (2) transferring a sample peptide or protein isolated on said gel to a hydrophobic synthetic resin membrane of open porous structure upon which said sample is adsorbed; (3) staining said sample adsorbed on said membrane; (4) dividing the membrane into strips bearing portions of the stained sample; (5) placing at least one of said strips into a cylindrical sequenator reaction chamber the longitudinal axis of at least one of said strips being substantially parallel to the longitudinal axis of said cylindrical reaction chamber; (6) placing the reaction chamber in a sequenator; and (7) subjecting the sample to sequence analysis.
Claim 3
Dependent Claim
32 words
The method of claim 1 in which the gel is a sodium dodecyl sulfate gel, the synthetic resin membrane is a polyvinyl difluoride membrane and the sample is stained with Coomassie Blue.
Claim 4
Dependent Claim
23 words
The method of claim 2 in which the membrane is formed from a combination of polyvinyl difluoride and a polymeric quaternary ammonium salt.
