Abstract
A simple method to produce biotinylated probes by utilizing an amine-psoralen to conjugate an ester-biotin to nucleic acid molecules is described. It is simple, rapid, and well suited to label cDNA probes with any PCR-generated amplicon for hybridization assay. Its application to identify or to confirm the G and P genotypes of rotavirus-derived amplicons is described; however, it may be used to label amplicons of any origin. As an alternative or as a complementary test to either PCR-typing assay and/or sequencing, it should reduce considerably the laboratory costs required to genotype fully virus strains in large epidemiological surveys conducted in developing countries.
