ABSTRACT
Highly Active Anti-Retroviral Therapy (HAART) has effectively inhibited the prevalence of HIV-1 and reduced the death rate caused by AIDS. In recent years,the emergence of resistance-conferring RT gene mutations in HIV-1 strains has become the major reason for HAART failure. The detection of drug resistance is important for the HAART regimen choice and novel drug development. A novel assay for the detection of HIV-1 RT drug resistance mutations was developed. HIV-1 drug resistance and wild strains in B subtypes were investigated using Two-Step Mutagenically-Separated PCR (MS-PCR),and point mutations including M41L,K70R,K103N,Y181C,T215F were detected. A longer mutant type primer was designed,using microplates hybridization and ELISA technique to detect several point mutations within a mixed mutant-wild type population. The results indicate that the Two-Step MS-PCR is as sensitive and specific as that in the traditional MS-PCR and MS-PCR combined with ELISA can give a good P/N quotient with better sensitivity,low cost,relatively less time consumption and high-throughput screening. It will be used in clinic usage for the detection of HIV-1 drug resistance mutations as well as other point mutations.
