fT4 (Free Thyroxine) ELISA Kit | G-EC-00053 | Gentaur Elisa Kits
Target Species: Universal
Assay Time: 2.5h
Detection Type: Colormetric
Detection Range: 1.56~100pg/mL
Target Name: fT4
Tested Sample Types: Serum, plasma and other biological fluids
Test Principle: 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 samples 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 ± 2 nm. The concentration of fT4 in the samples is then determined by comparing the OD of the samples to the standard curve.
Specificity: This kit recognizes fT4 in samples. No significant cross-reactivity or interference between fT4 and analogues was observed.
Application: This ELISA kit applies to the in vitro quantitative determination of fT4 concentrations in Serum, plasma and other biological fluids.
Research Areas: Signaling transduction, Developmental Biology
Storage: An unopened kit can be stored at 2-8℃ for 1 month. If the kit is not supposed to be used within 1 month, store the items separately according to the storage table in the manual once the kit is received.
