The method based on the combination of polymerase chain reaction (PCR) and
fluorescence polarization is presented. A targeted DNA was amplified with a
5'-fluorescein labeled primer, using a 256 bp DNA fragment of stx2 gene in
Escherichia coli O157:H7 (188-443 bp) as a template. The fluorescence
anisotropy of the 5'-fluorescein labeled primer increased upon the
polymerization through Taq polymerase. The conversion of primer to PCR
product was quantitatively monitored by anisotropy ratio and relative
hydrodynamic volume. This system was also applied to the determination of
E.coli O157:H7.
