An improved assay for an ATL virus antibody in a specimen, in which an ATL virus antigen is added to the test specimen and used as a comparative specimen. This improved method selectively assays ATL virus antibodies, and, thus, is useful in preventing and treating adult T cell leukemia.

Process for assaying ATL virus antibody and reagent therefor

Improved method for the measurement of substance comprising simultaneously measuring a plurality of specimens of a substance to be measured by enzyme immunoassay. The process comprises:

Method for measuring substances by enzyme immunoassay

A process for producing an adult T cell leukemia associated antigen is disclosed wherein an adult T cell leukemia associated antigen producing cell is treated with a surfactant. A method for assaying adult T cell leukemia associated antibodies by enzymoimmunoassay, radioimmunoassay or passive hemagglutination is also disclosed. In this method, the adult T cell leukemia associated antigen obtained by treating the adult T cell leukemia associated antigen producing cells with a surfactant is used as the antigen in the assay procedure.
