Briefly, the GP–PCR reaction was carried out using 50 ?l of PCR solution containing 10 m M Tris HCL pH 8.3, 50 m M KCl, dos00 ? M of each deoxynucleotide, 3.5 m M of MgCl2, 1 U of DNA polymerase (AmpliTaq; Perkin-Elmer, USA) and 25 pmol of each of the GP5+ and biotinylated GP6+ primers (Eurogentec, Belgium): 40 cycles of amplification were carried out using a Perkin-Elmer 9600,USA thermocycler.
