The TSH (Thyroid Stimulating Hormone) BioAssay™ ELISA Kit (Rabbit) is a quantitative competitive assay for the detection of TSH in serum, plasma, tissue homogenates and other biological fluids.
Sensitivity:0.188ng/ml
Detection Range:0.312-20ng/ml
Specificity:This assay has high sensitivity and excellent specificity for detection of rabbit TSH. No significant cross-reactivity or interference between TSH and analogues is observed.
Precision:Intra-Assay: CV<8%Inter-Assay: CV<10%
Test Principle:The microtiter plate provided in this kit has been pre-coated with TSH. During the reaction, TSH in the sample or standard competes with a fixed amount of TSH on the solid phase supporter for sites on the Biotinylated Detection Antibody specific to TSH. Excess conjugate and unbound sample or standard are washed from the plate, and HRP-Streptavidin (SABC) is added to each microplate well and incubated. Then TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm. The concentration of TSH in the samples is then determined by comparing the O D of the samples to the standard curve.
Storage and Stability:Store unopened kit at 4ºC; store at -20ºC once opened. Store unopened standard at 4°C; once reconstituted, store at 4°C for up to 12 hours or at -20°C for up to 48 hours. Store other components at 4°C. Kit is stable for 6 months after receipt. For maximum recovery of product, centrifuge the original vials after thawing and prior to removing the cap.
