Description			Tumor Necrosis Factor receptor type I (TNF-RI) is also referred as p60. The p60 form of the receptor is primarily expressed on epithelial cells. Recombinant human soluble TNF receptor Type I (sTNF-RI) contains 162aa residues comprising the extra cellular domain of TNF Receptor Type I. Source: Recombinant protein corresponding to soluble human TNF receptor Type I, expressed in E. coli. Molecular Weight: ~18.3kD Biological Activity: Determined by its inhibitory effect of the TNF-a mediated cytotoxicity in murine L-929 cells. The ED50 for the effect in the presence of 0.25ng/ml of recombinant TNF-a, is 0.05mg/ml. Endotoxin: <0.1ng/ug Storage and Stability: Lyophilized powder may be stored at -20°C. Reconstitute with sterile buffer. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Reconstituted product is stable for 6 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
