Human TNFR2 Protein

• Catalog Number: orb428900
• Category: Proteins
• Description: Recombinant of human TNFR2 protein
• Form/Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
• Buffer/Preservatives: TNFR2 was Lyophilized from a 0.2µm filtered concentrated solution in PBS, pH 7.4.
• Purity: Greater than 97.0% as determined by SDS-PAGE.
• Protein Sequence: MPAQVAFTPY APEPGSTCRL REYYDQTAQM CCSKCSPGQH AKVFCTKTSD TVCDSCEDST YTQLWNWVPE CLSCGSRCSS DQVETQACTR EQNRICTCRP GWYCALSKQE GCRLCAPLRK CRPGFGVARP GTETSDVVCK PCAPGTFSNT TSSTDICRPH QICNVVAIPG NASMDAVCTS TSPT
• Application notes: Cytokines And Growth Factors
• Source: Escherichia Coli
• Biological Activity: The ED50 as determined by its ability to inhibit the TNF-a mediated cytotoxicity in the L-929 cells is less than 0.2µg/ml, corresponding to a specific activity of > 5000IU/mg in the presence of 0.25ng/mL of rHuTNF-a.
• Solubility (25°C): It is recommended to reconstitute the lyophilized TNFR2 in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
• Storage: Stability: Lyophilized TNFR2 although stable at room temperature for 3 weeks, should be stored desiccated below -1°C. Upon reconstitution TNFR2 should be stored at 4C between 2-7 days and for future use below -1°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles
• Alternative names: Tumor necrosis factor receptor superfamily member
