Abstract:
1. A process for performing an immunoassay for detecting 5-fluoro-uracil in a sample comprising providing a mixture of a) a sample, b) an antibody selectively reactive with 5-fluoro-uracil which antibody is not substantially cross-reactive with tegafur and c) a conjugate of a carrier with a compound of the formula: wherein Y is an organic spacing group; X is a terminal functional group capable of binding to the carrier; and p is an integer from 0 to 1 or a compound of the formula: wherein X, Y and p are as above; or mixtures thereof; causing the 5-fluoro-uracil in the sample and said conjugate to bind with said antibody and thereafter measuring the amount of said conjugate in said mixture which is bound or unbound to said antibody whereby the presence of 5-fluoro-uracil in the sample can be determined.
