This enzyme produces the complementary DNA from the RNA (as template). These are purified by solubilising the virus with non-ionic detergents. Lysed virions are adsorbed on DEAE-cellulose or DEAE-Sephadex columns, and the enzymes are eluted with a salt gradient, then chromatographed on a phosphocellulose column and fractions with enzyme activity are eluted in a salt gradient. They are also purified from other viral proteins by affinity chromatography on a pyran-Sepharose column.
