You are enquiring about fT4 (Free Thyroxine) ELISA Kit
Description:
This ELISA kit applies to the in vitro quantitative determination of fT4 concentrations in serum, plasma and other biological fluids.
Assay Principles: This ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with fT4. During the reaction, fT4 in the sample or standard competes with a fixed amount of fT4 on the solid phase supporter for sites on the Biotinylated Detection Ab specific to fT4. Excess conjugate and unbound sample or standard are washed from the plate, and Avidin conjugated to Horseradish Peroxidase (HRP) are added to each microplate well and incubated. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color change is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The concentration of fT4 in the samples is then determined by comparing the OD of the samples to the standard curve.
Species reactivity:
Universal
Sample Type: Serum, plasma and other biological fluids
Storage instruction: -20˚C and 4˚C for 6 months
