The Bioaim Human CHI3L1 ELISA kit is a solid phase sandwich ELISA (enzyme-linked immunosorbent assay) for the quantitative measurement of CHI3L1 in Human serum, plasma and cell culture media. An antibody specific for Human CHI3L1 was coated on a 96-well plate. Standards and samples are added to the wells and any CHI3L1 present binds to the immobilized antibody. The wells are washed and biotinylated anti-Human CHI3L1 antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is added to the wells. The wells are again washed and TMB substrate solution is added, which produces a blue color in direct proportion to the amount of CHI3L1 present in the initial sample. The Stop Solution changes the color from blue to yellow, and the microwell absorbances are read at 450 nm.Research Area Angiogenesis; Cancer Biomarker;
Chitinase-3-like protein 1(CHI3L1) Background: Chitinase 3-like 1 (CHI3L1), also called BRP39 in mouse or YKL-40 in humans, is a 39 kDa glycoprotein member of the glycosyl hydrolase 18 family although it does not show chitotriosidase activity. CHI3L1 is expressed by articular chondrocytes, synovial cells, activated monocyte-derived macrophages, neutrophils, endothelial cells, vascular smooth muscle cells, and some cancer cells. CHI3L1 binds to chitin and heparins, and it enhances cell adhesion, proliferation and tumor angiogenesis. Circulating CHI3L1 is elevated during inflammation and connective tissue remodeling such as arthritis, chronic obstructive pulmonary disease, diabetes, cardiovascular disease, inflammatory bowel disease, and liver cirrhosis. It is frequently upregulated in glioblastoma, myxoid chondrosarcoma, melanoma and carcinomas of the breast, thyroid, colon, lung, kidney, and ovary.
