Anti-CHI3L1 Antibody

This polyclonal rabbit antibody targets CHI3L1, a secreted glycoprotein widely studied as the YKL-40 biomarker in inflammatory and oncology research. Raised in rabbit and supplied as an unconjugated 100 µl vial, the reagent is validated for Western blot and immunohistochemistry on human and rat tissue samples. Researchers investigating asthma, chronic obstructive pulmonary disease, osteoarthritis, glioblastoma, breast cancer, and other conditions where YKL-40 expression is elevated can use the antibody to probe cell lysates and fixed sections for the ~40 kDa target band. The polyclonal format improves tolerance for minor epitope variation across isoforms and post-translational modifications that CHI3L1 carries in vivo.
