We recently described the isolation of 2'-fluoropyrimidine-substituted RNA aptamers that bind specifically to the surface glycoprotein (gp 120) of the R5 strain, HIV-1(Ba-L), as presented in a previous study. These aptamers potently neutralize HIV-1 infectivity in human peripheral blood mononuclear cells of both tissue culture lab-adapted strains and diverse R5 clinical isolates from multiple clades. Here, we report a detailed structural characterization of one such neutralizing aptamer, B40,...Expand abstract
