Description
The Quantikine® QuicKit™ Human TNF RI/TNFRSF1A Immunoassay is a one step, 80-minute solid phase ELISA designed to measure human TNF RI levels in cell culture supernates, serum, plasma, and urine. It contains E. coli-expressed recombinant human TNF RI and antibodies raised against the recombinant protein. Results obtained for natural human TNF RI showed linear curves that were parallel to the standard curves obtained using the recombinant QuicKit™ standards. These results indicate that this kit can be used to determine relative mass values for natural human TNF RI
