The biological activity of Activin B is measured by its ability to inhibit mouse plasmacytoma cell line (MPC-11) cells proliferation.
<5ng/mL are required to stimulate a half-maximal response at cytokine saturation. Note: Since applications vary, each investigator should titrate the reagent to obtain optimal results.
Lyophilized from 1mg/ml solution in Tris HCl 0.05M buffer at pH 7.4.
Sterile Filtered White lyophilized (freeze-dried) powder.
Greater than 97.0% as determined by Analysis by SDS-PAGE.
The protein was electrophoresed under reducing condition on a 15% SDS-polyacrylamide gel, transferred by electro blotting to a NC membrane and visualized by immune-detection with specific Activin B antibody.
It is recommended to reconstitute the lyophilized Activin B in sterile 18MΩ-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Nicotiana benthamiana plant
Lyophilized Activin B although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution Activin B should be stored at 4oC between 2-7 days and for future use below -18oC. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
