FIELD: chemistry.
SUBSTANCE: invention relates to biosensors and can be used in studying proteins via a luminescence technique. A protein luminescence-activating hybrid complex is obtained through ultrasonic treatment of a protein which contains aromatic amino acids in a physiological solution in the presence of phosphorus Y0.95Hr0.05VO4 or Y0.95Er0.05YO3Cl. The complex contains donor-acceptor pairs.
EFFECT: use of the invention increases luminescence of the investigated protein and reduces labour input of the protein labelling procedure, widens the range of proteins analysed using a luminescence technique, and lowers the technological level of the process of obtaining donor-acceptor pairs in the protein luminescence-activating hybrid complex.
