Product Information
| Description: | Recombinant mouse/rat transforming growth factor β1 is produced by the mammalian expression system and the target gene encoding Ala279-Ser390 is expressed. Measured by its ability to inhibit IL-4-dependent proliferation of TF‑1 human erythroleukemic cells.The ED50 for this effect is 5-25 pg/ml. |
| 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. |
