Anti-YKL40 antibodies are used in antigen-specific immunodetection in biological samples. The target YKL40 is a known alias name of the protein chitinase 3 like 1, encoded by the CHI3L1 gene in humans. This 383-amino acid residue protein is known to be involved in the apoptotic pathway and carbohydrate metabolism and homeostasis, among other biological processes. It is localized to the ER, cytoplasm, and is secreted of the cell and features glycosylated post-translational modifications. Other synonyms for YKL40 include ASRT7, CGP-39, and GP-39. Western Blot is a widely used application for the YKL40 antibodies listed below. In addition, Immunohistochemistry is also a common application.
