Hi Maysaa. I rather use type specific primers in case of HPV 16 and HPV 18. These sets are old, but are based in very conserved sequences from genes E6 and E7, so they still work. Remember PGMY primers are consensus, so they will amplify every HPV genotype they find in the sample. They work, but you'll have to check with a probe or sequencing if the amplicon belongs to HPV 16 or HPV 18.
I am sending you the references, since I dont have my laptop with the pdf files. Also I am sending you a table with the sequences of the mentioned primers.
Best,
Vanessa

Many thanks for you. I really appreciate you detailed answer. but my concern is if I use specific primers for HPV-16 and 18, I afraid to miss another HPV high risk types like 33, 58, 34,62,....etc.
So I think I have to use the primers of L1 (conservative) then make a genotyping or sequencing....
