Description
The ST2 Human ELISA Kit from Arbor Assays delivers quantitative measurement of soluble ST2 (sST2) in serum, plasma, and tissue culture media, enabling high-sensitivity detection of this important cardiovascular and inflammatory biomarker. sST2 plays a role in immune signaling and is elevated in conditions such as heart failure, asthma, and autoimmune disease. This sandwich-format assay features a sensitivity of 30.5 pg/mL and a broad detection range of 31.25–2,000 pg/mL, with minimal cross-reactivity to other IL-1 receptor family members. The kit's 3-hour protocol supports efficient and accurate biomarker analysis across both clinical and translational research settings
