[Chemiluminescence in a toluene-fenoxol scintillation system in the radioreceptor method of researching biological membranes].

The scintillation toluene-fenoxol 8/10 system with ammonia (0.01%) is suggested for radioactive counting in radioreceptor biomembrane assay. It is shown that chemiluminescence in this system is defined mainly by membrane components presence. The remotion of filter from scintillator after labelled molecules elution and methanol (3%) addition to scintillation mixture are suggested to reduce the chemiluminescence level.
