[Isolation of the heterodimer of porcine MB creatine phosphokinase and the study of its binding with polyclonal antibodies].

Heterodimers of porcine creatine phosphokinase were obtained from dissociated MM and BB isoenzymes and investigated in the enzyme-linked immunosorbent assay. It has been shown that peroxidase conjugates of rabbit polyclonal antibodies against porcine enzymes have low affinity in the sandwich reaction.
