ABSTRACT:
The invention relates to a carrier-drug conjugate comprising a carrier containing a polypeptide sequence having one or several cysteine radicals and a pharmacon containing a pharmaceutical and/or diagnostic active substance, a spacer molecule and a thiol binding group, whereby over 0.7 mol pharmacon per mol of cysteine radical is bound to the carrier by the thiol binding group. The invention also relates to a method for the production of said conjugate and to medicaments and diagnostic kits containing said conjugate.
