Activin-B Human Recombinant, Active
| 目录号 | AP3334 |
|---|---|
| Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation | Lyophilized from 1mg/ml solution in 0.05M Tris-HCl buffer pH 7.4. |
| Protein biological activity | The biological activity of Activin B is measured by its ability to inhibit mouse plasmacytoma cell line (MPC-11) cells proliferation. EC50 <5ng/ml is required to stimulate a half-maximal response at cytokine saturation. Note: Since applications vary, each investigator should titrate the reagent to obtain optimal results. |

| Uniprot ACC# | P09529 |
| Purity | Greater than 97.0% as determined by Analysis by SDS-PAGE. |
| Solubility | It is recommended to reconstitute the lyophilized Activin B in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. |
| Stability | Lyophilized Activin B although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Activin B should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles. |
