[Immunoenzyme method of determining thymus polypeptide factor].

A rapid indirect enzyme immunoassay technique for the determination of thymalin, a polypeptide thymus factor, with sensitivity equal to 1.5 X 10(-8) mol/l has been developed. The accuracy of determinations, measured by the variation factor, has proved to be 5-10% in the interassay, 10-15% in the interassay, the reliability in the opening test being 5%. The assay takes 4.5-5 hours.
