The microtiter plate provided in this kit has been pre-coated with Rat T4 antigen, and the Rat T4 standard plate wells that pre-coated using protein-related techniques are provided separately. Standard\/Sample Diluent Buffer or samples are added to the appropriate microtiter plate wells ,then added a HRP-conjugated antibody specific to Rat T4 to each microplate well and incubated . After TMB substrate solution is added, the enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ±10nm. The concentration of Rat T4 in the samples is then determined by comparing the OD of the samples to the standard curve.","StandardCurveURL":"https:\/\/www.elkbiotech.cn\/upload\/image\/ELISA\/ELK056ES-b-1.jpg","ManualURL":"https:\/\/www.elkbiotech.cn\/upload\/file\/ELISA\/ELK056ES-1.pdf","ProductURL":"https:\/\/www.elkbiotech.cn\/pro\/ELK056ES",}
