General description

YKL-40 (Chitinase-3-like protein 1; human cartilage glycoprotein 39) is a secreted glycoprotein belonging to the glycosyl hydrolase 18 (GH18) family. It is found primarily in chondrocytes, activated macrophages, and hepatocytes. The precise biological function of YKL-40 is still unknown; however, recent studies suggest that YKL-40 may play a role in cell differentiation and inflammation. YKL-40 is elevated in the sera of patients with inflammatory diseases or cancer, and it is currently being investigated as a potential biomarker for these conditions.

Immunogen

Recombinant protein corresponding to human Chitinase-3-like protein 1 (YKL-40).

Application

Immunocytochemistry Analysis: A representative lot from an independent laboratory detected Chitinase-3-like protein 1 (YKL-40) in U87 cells (This protein blocks tumor angiogenesis tube formation and progression (Faibish, M., et al. (2011). Mol Cancer Ther. 10(5):742-751.)).

Activity Assay Analysis: A representative lot from an independent laboratory neutralized Chitinase-3-like protein 1 in a neutralization assay (Faibish, M., et al. (2011). Mol Cancer Ther. 10(5):742-751.).
