Tech Info / Data

Background: 

The Human IFN Alpha Sampler Set provides a collection of 12 distinct biologically active alpha interferons which enables studies of their activity in various applications.

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 on the role interferons have in an immunological event, but can also lead to the refinement of current interferon based therapeutic applications.
