Product Information
| Description: | Fm-479 was a negative control of FM-381 and showed no activity against JAK3 or other kinases. Fm-381 is a potent covalent reversible inhibitor of JAK3 targeting unique Cys909. For JAK3, FM-381 was 410, 2700 and 3600 times more selective than JAK1, JAK2 and TYK2 with IC50 of 127 pM. |
| Stability and Solubility Advice: | Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide. We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details. |
