Interferon alpha A and D are produced by macrophages, IFN-alpha have antiviral activities. Interferon stimulates the production of two enzymes: a protein kinase and an oligoadenylate synthetase. Interferon-Alpha A/D Bg/II is an alpha interferon hybrid that crosses the species barrier. The Bg/II denotes the restriction enzyme site from which this hybrid is constructed from recombinant human interferons Alpha A and Alpha D. Interferon-Alpha A/D has been proven to be active on many mammalian cells. It can substitute for human, monkey, mouse, bovine, rat, cat, dog, rabbit, sheep, goat, horse, pig or hamster type I interferon (alpha, beta, omega and tau). Alternative Names: Interferon alpha D protein
