Human ZNRF2 ELISA kit is a sandwich Enzyme-Linked Immunosorbent Assay (sELISA) designed for the in vitro quantitative determination of human ZNRF2 in serum, plasma, tissue homogenates, and other biological fluids.

• Ready-to-use ELISA kit
• Assay precision: Intra-assay: CV <8%, Inter-assay: CV <10%

Human ZNRF2 ELISA kit employs the sandwich enzyme immunoassay technique for the quantitative measurement of human ZNRF2 in serum, plasma, tissue homogenates, and other biological fluids. An antibody specific for ZNRF2 has been pre-coated onto a 96-well microtiter plate. The standards and test samples are added into the wells and the ZNRF2 present in each sample is bound to the wells by the immobilised antibody. Following incubation, the wells are washed and then incubated with Biotinylated Anti-ZNRF2 Antibody, which binds the captured ZNRF2 present in each well. Following incubation, unbound biotinylated detection antibody is removed by washing, and an HRP-Streptavidin conjugate is added to the wells and the microtiter plate is incubated. Following incubation and washing, TMB substrate solution is then used to visualise the HRP enzymatic reaction by catalysis to produce a blue-coloured product that changes to yellow after addition of acidic stop solution. The density of yellow is proportional to the amount of ZNRF2 captured in each well. The concentration of ZNRF2 can then be calculated by reading the O.D. absorbance at 450 nm in a microplate reader and referring to the standard curve.
