Human IL-1rl1 ELISA Kit (HUEB0081)

From Assay Genie, this Sandwich ELISA Kit is intended for the quantitative detection of human Interleukin-1 receptor-like 1 (IL1RL1), also referred to as Protein ST2, ST2, DER4, and T1 (UniProt Q01638). The assay is reactive with human samples, including serum, plasma, tissue homogenates, cell culture supernates, and other biological fluids, and is supplied for research use only within the immunology research area.

Using a colorimetric detection method, the kit is specific for natural and recombinant human IL1RL1, with a detection range of 31.2-2000pg/mL and a reported sensitivity of 15.69pg/mL. Precision figures include an intra-assay CV of 5.3% and an inter-assay CV of 10.3%, with linearity validated across dilutions from 1:2 to 1:16 in serum, EDTA plasma and heparin plasma. Documented recovery values are 101% (range 95-107%) for serum and 103% (range 97-109%) for plasma. IL1RL1 is a single-pass type I membrane protein belonging to the interleukin-1 receptor family and serves as the receptor for IL-33, with isoform B functioning to inhibit IL-33 signalling.
