Characterization of the AIDS-associated retrovirus reverse transcriptase and optimal conditions for its detection in
Virology
|December 1, 1985
Abstract:
The RNA-dependent DNA polymerase of the AIDS-associated retrovirus (ARV) gives highest activity with the synthetic template, poly(rA)oligo(dT) and prefers Mg2+ over Mn2+ as a divalent cation. It can use other template-primer combinations but with poly(rCm)oligo(dG), it prefers Mn2+ over Mg2+. Detection of ARV reverse transcriptase in culture fluids is substantially increased with an optimal KCl concentration and a special combination of EGTA and reducing agents. Our results indicate some distinguishing characteristics of the ARV reverse transcriptase and optimal conditions for its detection.
