Description

Product Name:Human sST2 (Soluble ST2) ELISA Kit
Product Code:AEES00118
Assay Type:Sandwich
Format:96T
Assay Time:3.5h
Reactivity:Human
Detection Range:0.31-20 ng/mL
Sensitivity:0.19 ng/mL
Sample Type & Sample Volume:Serum, plasma and other biological fluids, 100μL
Specificity:This kit recognizes Human sST2 in samples. No significant cross-reactivity or interference between Human sST2 and analogues was observed.
Reproducibility:Both intra-CV and inter-CV are < 10%.
Application:This ELISA kit applies to the in vitro quantitative determination of Human sST2 concentrations in serum, plasma and other biological fluids.

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human sST2. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human sST2 and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Human sST2, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Human sST2. You can calculate the concentration of Human sST2 in the samples by comparing the OD of the samples to the standard curve.
