Human Activin B Active Protein

SKU: orb167848

Description

Recombinant of Human Activin B Active protein

Images & Validation

−

Application Notes	Cytokines And Growth Factors

Key Properties

−

Source	Nicotiana benthamiana plant
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.

Purity	Greater than 97.0% as determined by Analysis by SDS-PAGE.

Storage & Handling

−

Storage	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
Form/Appearance	Sterile Filtered White lyophilized (freeze-dried) powder.
Buffer/Preservatives	Lyophilized from 1mg/ml solution in 0.05M Tris-HCl buffer pH 7.4.
Disclaimer	For research use only

Alternative Names

−

Inhibin beta B (activin AB beta polypeptide), Inhibin, beta-2, Activin beta-B chain, MGC157939.
