Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
66 words
A process for the fixing or insolubilizing of proteins, which process comprises bonding a protein to a condensation product obtained according to the process which comprises reacting a carbocyclic, aromatic polyamine or 3-methylmercaptoaniline with an aliphatic dialdehyde having up to 6 carbon atoms or acrolein to give a condensation product suitable for the fixing or insolubilizing of proteins, excluding the manufacture of the 1,3-phenylenediamine-glutardialdehyde condensation product.
Claim 2
Dependent Claim
66 words
A process for the fixing or insolubilizing of proteins, which process comprises bonding a protein to a condensation product obtained according to the process which comprises reacting a carbocyclic, aromatic polyamine or 3-methylmercaptoaniline with an aliphatic dialdehyde having up to 6 carbon atoms or acrolein to give a condensation product suitable for the fixing or insolubilizing of proteins, excluding the manufacture of the 1,3-phenylenediamine-glutardialdehyde condensation product.
