Recombinant sTNFR-I comprises a 161 amino acid fragment (41-201) corresponding to the mature sTNFR-I protein and is expressed in E. coli with an amino-terminal hexahistidine tag.

Two types of soluble TNF receptors (sTNFR-I and sTNFR-II) have been identified, which act to neutralize the biological activities of TNF alpha and TNF beta. Levels of these soluble receptors appear to arise as a result of shedding of the extracellular domains of the membrane bound receptors.

Applications:
Suitable for use in ELISA. Other applications not tested.

Recommended Dilution:
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile glycerol (40-50%), aliquot and store at -20C. Aliquots are stable for at least 12 months at -20C. 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.
