Human ST2 ( Suppression Of Tumorigenicity 2) Microsample ELISA Kit

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human ST2. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human ST2. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Human ST2, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Human ST2 in the samples is then determined by comparing the OD of the samples to the standard curve.Detection Range: 0.16-10 ng/mL. Sensitivity: 0.06 ng/mL. Assay Type: Sandwich. Standard: 10 ng/mL. Sample Type: sserum, plasma, tissue homogenates, cell lysates and other biological fluids. Assay duration: 3.5h. Protein Function: Receptor for interleukin-33 (IL-33) which plays crucial roles in innate and adaptive immunity, contributing to tissue homeostasis and responses to environmental stresses together with coreceptor IL1RAP (PubMed:35238669). Its stimulation recruits MYD88, IRAK1, IRAK4, and TRAF6, followed by phosphorylation of MAPK3/ERK1 and/or MAPK1/ERK2, MAPK14, and MAPK8. Possibly involved in helper T-cell function (Probable) (PubMed:16286016). Upon tissue injury, induces UCP2-dependent mitochondrial rewiring that attenuates the generation of reactive oxygen species and preserves the integrity of Krebs cycle required for persistent production of itaconate and subsequent GATA3-dependent differentiation of inflammation-resolving alternatively activated macrophages (By similarity) , Inhibits IL-33 signaling [The Uniprot Consortium]
