ABSTRACT:
In diagnostic testing for cancer and precancer of the epithelium, the undesired binding of cancer-selective dyes to proteins in the extracellular matrix, which may lead to false positives, is reduced by applying to the epithelium being tested, before application of the dye, a solution of a non-toxic amphiphilic protein in a pharmacolgically acceptable solvent.
