Human RED ELISA kit employs the sandwich enzyme immunoassay technique for the quantitative measurement of human RED in serum, plasma or other biological fluids. An antibody specific for RED has been pre-coated onto a 96-well microtiter plate. The standards and test samples are added into the wells and the RED present in each sample is bound to the wells by the immobilised antibody. Biotinylated Anti-RED antibody, which also binds the RED present in each sample, and Streptavidin-HRP, which binds the Biotinylated Anti-RED antibody, are added and the microtiter plate is incubated. Following incubation, unbound Biotinylated Anti-RED antibody and unbound Streptavidin-HRP are removed by washing, and two substrate solutions are added to the wells. Colour develops in proportion to the amount of RED captured in each well. The colour development is stopped by addition of stop solution which changes the colour from blue to yellow and the intensity of the colour is then measured. The concentration of RED in the samples can then be calculated by reading the O.D. absorbance at 450 nm in a microplate reader and referring to the standard curve.
