  • Relevance
    TNF RI (CD120a) is a 55 kDa transmembrane glycoprotein that is expressed by virtually all nucleated mammalian cells. Among the numerous cells known to express TNF RI are hepatocytes, monocytes and neutrophils, cardiac muscle cells, endothelial cells, and CD34+ hematopoietic progenitors. Both TNF alpha and TNF beta bind to TNF RI. Soluble TNF alpha binds with a Kda in the range of 20-60 pM, while TNF beta binds with a Kda equal to 650 pM. TNF RI relative to TNF RII seems to be the more physiologically relevant receptor, whereas TNF R2 appears to play a direct role in only a limited number of TNF responses. Soluble TNF RI, which blocks TNF alpha activity, has been identified in both urine and blood (1-3 ng/mL). Serum levels of sTNF receptors increase dramatically in certain pathological situations.

Answer

Thank you for your enquiry. Please see the reconstitution protocol below: Centrifuge the vial prior to opening. Reconstitute in 5 mM Tris pH 8.0 to a concentration of 0.1-1.0 mg/ml. This solution can then be diluted into other aqueous buffers and stored at 4oC for 1 week or -20oC for future use. I hope this information helps, please do not hesitate to contact us if you need any more advice or information.

Question

Good morning, I orderd lyophilized, soluble TNF R1 protein (ab9980) and the datasheet does not indicate what the resuspension buffer is. Will you please send me that information? Thank you,
