A competitive inhibition test of enzyme immunoassay for the anti-nRNP antibody.
A competitive inhibition test for anti-nRNP antibody was developed, using horseradish-peroxidase-labelled anti-nRNP IgG derived from the serum of a patient with mixed connective tissue disease. In this test, the anti-nRNP antibody was clearly distinguished from the anti-Sm antibody in the patients' sera, and the sensitivity of the assay for anti-nRNP antibody was close to 50 ng/ml.
