Tech Info & Data



The Human interferon alpha protein family consists of 12 individual protein species, each with reported different biological properties. Some have proven to be 10 and 20 times more effective than Human IFN-alpha A in protecting a cell against specific viruses. Elucidating the functional significances of various IFN-alpha subtypes not only can lead to a better understanding of the role interferons have in an immunological event, but can also lead to the refinement of current interferon-based therapeutic applications.
