To date, pharmaceutical companies produce several types of recombinant and pegylated IFNα for clinical use; e.g., IFNα2a (Roferon-A, Roche), IFNα2b (Intron-A, Schering-Plough) and pegylated IFNα2b (Sylatron, Schering Corporation) [2] for treatment of hairy cell leukemia, melanoma, renal cell carcinoma, Kaposi's sarcoma, multiple myeloma, follicular and non-Hodgkin lymphoma, and chronic myelogenous leukemia [2,4,5]. Here, IFNA2 is linked to non-Hodgkin lymphoma.
