Used in research and diagnostic applications to detect and quantify CHI3L1 (Chitinase-3-like protein 1), a biomarker associated with inflammation, tissue remodeling, and cancer progression. This antibody enables precise targeting of CHI3L1 in immunoassays such as ELISA, Western blot, and immunohistochemistry, supporting studies on diseases like asthma, rheumatoid arthritis, and various cancers including glioblastoma and colorectal carcinoma. It is also employed in therapeutic development to evaluate target engagement and mechanism of action in preclinical models. Its high specificity makes it valuable for distinguishing CHI3L1 from other chitinase-like proteins in complex biological samples.
