Human CHI3L1 ELISA Kit

CHI3L1 (Chitinase 3-like 1), commonly referenced in the literature as YKL-40, is a secreted glycoprotein of approximately 40 kDa that is studied extensively as a biomarker of inflammation, tissue remodeling, and tumor progression. This Antibodies.com kit provides the core components needed to quantify human CHI3L1 levels in experimental research samples using a quantitative immunoassay workflow. Investigators working on osteoarthritis, asthma, hepatic fibrosis, glioblastoma prognosis, and cardiovascular disease routinely track circulating CHI3L1 as an indicator of macrophage activation and extracellular matrix turnover.

The reagents are supplied in a 96-test kit format suitable for generating full standard curves alongside sample replicates on a standard microplate reader. Capture antibody, biotinylated detection antibody, recombinant human CHI3L1 reference standard, streptavidin-HRP conjugate, and the color development substrate required to produce measurable signal are all included. A step-by-step assay protocol and recommended plate layout are provided with each kit to support reproducible inter-assay comparisons across study cohorts. Intended for research use only.
