Abstract
Biologically active proteins are immobilized onto a carrier by reacting a compound containing at least two secondary amino groups at a temperature of from -80.degree. to +50.degree. C with a chlorination agent with the conversion of the secondary amino groups into iminochloride groups of the formula ##STR1## in which R and R.sub.1, which can be the same or different, are aliphatic, aromatic or aliphatic-aromatic radicals, and reacting the carrier material product thus obtained
