Human Chitinase 3-like 1/YKL-40 ELISA Kit - 1 Kit (96 Wells)Our Human Chitinase 3-like 1/YKL-40 ELISA Kit is a sandwich ELISA intended for the quantitative determination of human Chitinase 3-like 1 in cell culture supernates, serum, plasma (heparin, EDTA) and urine.
Chitinase-3-like protein 1, also called CHI3L1 or YKL-40 is a secreted glycoprotein that is approximately 40kDa in size that in humans is encoded by the CHI3L1 gene. This gene is mapped to 1q32.1. Chitinases catalyze the hydrolysis of chitin, which is an abundant glycopolymer found in insect exoskeletons and fungal cell walls. The glycoside hydrolase 18 family of chitinases includes eight human family members. This gene encodes a glycoprotein member of the glycosyl hydrolase 18 family. The protein lacks chitinase activity and is secreted by activated macrophages, chondrocytes, neutrophils and synovial cells. The protein is thought to play a role in the process of inflammation and tissue remodeling.
