  • Product overview

    Abcam’s Human STNF-R1 (soluble tumor necrosis factor receptor I) ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human STNF-R1 in serum, plasma and cell culture supernatants.

    This assay employs an antibody specific for Human STNF-R1 coated on a 96-well plate. Standards and samples are pipetted into the wells and STNF-R1 present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human STNF-R1 antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of STNF-R1 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

It is not known whether this kit will detect the TNF-sTNFR1 complex or not. We know it will detect free soluble TNF R1 and it does not cross react with TNF-alpha, TNF-beta or soluble TNF RII. Whether though the kit will detect soluble TNF R1 complexed with one of these ligands though has not been tested.

Thank you for your enquiry regarding these kits.

I would suggest reading through the Protocol Booklets for each of these kits provided on the product datasheets. These documents contain specific information about the sample types, sample preparations, protocol, instruments and equipment required for the assays. Whole blood samples are not used to test these kits mainly serum or plasma instead.
