Product Info

Universal Type I IFN-Alpha is a unique hybrid interferon constructed from recombinant human interferons alpha A and alpha D (Human IFN-Alpha A/D [BglII]). Activity has been observed on many mammalian cells, including human, monkey, mouse, bovine, rat, cat, pig, rabbit, guinea pig, or hamster.


This product is useful for cross-species testing with interferon or for species where autologous interferon is not available. Crucial for cross-species comparative studies in virology, immune modulation, and more.
