“…DNA samples sent from Cambodia were amplified using PGMY09/11 primers for HPV L1 region and HLA primer as internal control and the PCR products were used for reverse blotting hybridization (PGMY-CHU assay). 4,5 In this assay, 31 HPV types (HPV6, 11,16,18,26,31,33,34,35,39,40,42,44,45,51,52,53,54,55,56,57,58,59,66, 68, 69, 70, 73, 82, 83 and 84) were detected. Our genotyping quality was equivalent to that of genotyping system used in the National Institute of Infectious Diseases in Japan, which had been evaluated as proficient in the HPV DNA proficiency panel study conducted by WHO HPV Laboratory Network.…”
