[Anti-C100-3 antibody titration using 4-parameter logistic curve (results in its application to hepatitis C cases treated with interferon].
We evaluated titers of C100-3 antibody by ELISA using a 4-parameter logistic fitting curve and examined the transition of the values in the cases of interferon treatment. The 4-parameter logistic fitting curve produced a standard curve in a wider range using a micro plate reader than the logarithmic curve. The values of C100-3 antibody during and after the treatments of interferon were changed in parallel with the alterations of ALT. The anti-C100-3 antibody titers assayed in the complete or partial responders were significantly reduced at the end of interferon therapy. These findings suggest the clinical usefulness of the evaluation of anti C100-3 antibody titers.
