title: Comparisons of dose-response data for various standard and recombinant DNA-derived human interferons.
abstract: Dose responses of the NIH standard IFN-alpha and IFN-beta preparations were compared with recombinant DNA-derived IFN-beta (IFN-beta 1) and various IFN-alpha subtypes, molecular hybrids and mixtures. Cytopathic effect assays were employed using vesicular stomatitis virus on human HeLa and bovine MDBK cells. A natural peripheral blood lymphocyte and recombinant DNA-derived IFN-gamma were also included in the comparisons. Two-tailed t-tests between slopes showed no significant differences in any pair-wise comparison using crude or highly purified preparations.
