Interferon is a high molecular weight protein. Small groups of proteins with a molecular weight of 20,000-30,000 daltons are called interferons. It is a protective protein. Interferon is produced by E. coli and yeast. The commercial name of interferon is Betaferon. It is of three types. α-interferon β-interferon and γ-interferon.
