FIELD: analytical methods. SUBSTANCE: label represents particles of catalytically active metals 0.003-0.1 mcm in size, capable of depositing metals from solutions of physical developers on their surface. Mentioned particles are attached to particles of inert carrier 0.1-10 mcm in size characterized by density of 1.0-1.5 g/cu.cm. EFFECT: reduced price and simplified preparation of diagnosticum, increased sensitivity of label and accelerated assay procedure. 4 cl, 4 ex
