TNFR2 Human Fc

Data sheet

Formulation

Each mg contains 1.6mg mannitol, 0.4 mg sucrose and 48 ug tromethamine.

Solubility

It is recommended to reconstitute the lyophilized TNFR2 in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Purity

Greater than 98.0% as determined by:(a) Analysis by RP-HPLC.(c) Analysis by SDS-PAGE.

Description

Recombinant Human Tumor Necrosis Factor Receptor 2 Fusion Protein produced in CHO is a dimeric, glycosylated, polypeptide chain consisting of the extracellular ligand-binding portion of the human 75 kilo Dalton (p75) tumor necrosis factor receptor 2 (TNFR

Protein Background

TNFR binds specifically to tumor necrosis factor (TNF) and blocks its interaction with cell surface TNF receptors. TNF is a naturally occurring cytokine that is involved in normal inflammatory and immune responses. It plays an important role in the inflam

Expression host

Chinese Hamster Ovarian Cells (CHO).

Reagent Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Stability

Lyophilized Tumor Necrosis Factor Receptor although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution TNFR2 should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it

Biological Activity

Potency is determined by its ability to neutralize TNF-alpha mediated growth inhibition of A375 cells, corresponding to a Specific Activity of 17,000,000 IU/mg.
