BIOLOGICALLY ACTIVE PROTEIN AND A PROCESS FOR THE PREPARATION THEREOF

摘要

A biologically active protein or protein substrate bound on to polyamide nylon is provided. The material is bound by the group of the general formula: in which R and R1, which may be the same or different, are polyamide residues bound on to the amido group, R2 is a residue of a compound which can be condensed with formaldehyde and which contains at least one further reactive group, R3 is the residue of a bi- or poly-functional protein reagent, n is O or 1 and P is a biologically active protein, and is obtainable by the reaction of a polyamide with amounts, equimolar to one another, of formaldehyde and of the compound which can be condensed with formaldehyde in a solvent for polyamides, reaction of the product thereby obtained with a bi- or polyfunctional protein reagent and coupling of the so obtained product with a biologically active protein or protein substrate.
