SULT1A1 and infection: In order to determine the specific stage of HIV-1 reverse transcription that is influenced by SULT1A1, MDMs were transfected with SULT1A1-specific or control siRNA prior to infection with VSV-G pseudotyped NL43-Luc HIV-1 vector and DNA was isolated at different time points post-infection (ranging from 8–24 h).
