[Soluble high molecular weight derivatives of pancreatic trypsin inhibitor. Effect of electrostatic interaction of protein with the carrier on covalent binding and some physico-chemical properties of modified preparations of pancreatic inhibitor].
Modification of pancreatic trypsin inhibitor by carboxymethyl dextran with the aid of carboxyl groups of the carrier activated by water-soluble carbodiimide has been carried out. A special role of electrostatic interactions of protein with the carrier during inhibitor modification has been shown. This modification results in active preparations with high protein concentration on the carrier; their molecular weight is practically equal to that of previously used carrier. A comparison of the thermal stability of high molecular weight preparations of pancreatic inhibitor with respect to protein concentration on the carrier and the number of links between protein and carrier has been carried out.
