Mini Sample Human sST2 (Soluble ST2) ELISA Kit

• Abbreviation:

  SST2

• UniProt:

  Q01638

• Cross Reactivity:

  This kit recognizes sST2 in samples.No significant cross-reactivity or interference between sST2 and analogues was observed.

• Target:

  DER4; FIT-1; Growth stimulation expressed gene 2; IL-1R4; IL1RL1; IL33R; ST2

• Type:

  Sandwich-ELISA

• Applications:

  ELISA

• Field of Research:

  Immunology

• Assay Principle:

  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 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 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 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 sST2 . You can calculate the concentration of sST2 in the samples by comparing the OD of the samples to the standard curve.
