| Description : |
The interferon alpha 2A (IFN-α2A) is type I interferon. IFN-α 2A is produced by macrophages, peripheral blood leukocytes and lymphoblastoid cells. Proteins of this family play an important role in inducing non-specific resistance against a broad range of viral infections. IFN-α 2A has wide biological activities ranging as antiproliferation, immunomodulation, and antiviral. IFN-α 2A also affects cell proliferation and modulate immune responses, and regulates expression of MHC class -I antigens. |
| Bio-activity : |
The activity was measured by its ability to stimulate the proliferation of human TF-1 cells (human erythroleukemic indicator cell line). |
