A modified non-radioactive single strand conformation polymorphism ana
lysis incorporating a temperature gradient (TG-SSCP) and temperature g
radient gel electrophoresis (TGGE) were evaluated for the detection of
human papillomavirus type 6 (HPV 6)-variants in 41 condylomata acumin
ata and 5 Buschke-Loewenstein tumours. TG-SSCP and TGGE analysed part
of the transforming ORF E6 of HPV 6 spanning nucleotides 10 to 495. TG
-SSCP distinguished between 8 HPV 6-variants whereas TGGE demonstrated
6 different DNA-species. HPV 6-strains found in Buschke-Loewenstein t
umours did not vary in the analysed portion of the E6 ORF as compared
to ordinary condylomata acuminata. TG-SSCP and TGGE further showed abs
ence of double infection with different HPV 6-strains in the analysed
samples. Our results demonstrated that both methods may be successfull
y used for the detection of different strains of microbiological agent
s, although TG-SSCP seemed to provide easier execution and to confer a
higher degree of flexibility than TGGE.
