Recombinant Human Inhibin beta B Protein (N-terminal His Tag) (A63085)

The biological activity of Activin B is measured by its ability to inhibit mouse plasmacytoma cell line (MPC-11) cells proliferation. EC50 <5 ng/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.

>97% as determined by SDS-PAGE.

Lyophilized

1 mg/ml

Lyophilized from 50 mM Tris HCl Buffer, pH 7.4.

Shipped at ambient temperature. Lyophilized: Short term (3 weeks) store at 25°C. Long term store desiccated below -18°C. Reconstituted: Short term (2-7 days) store at 4°C. Long term store below -18°C, it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid freeze/thaw cycles.
