Key elements and design rationale
- Antibody format: Rabbit Polyclonal Rabbit IgG
- Immunogen / epitope context: E. coli-derived mouse CHI3L1 recombinant protein (Position: Y30-K262). (reported region: Y30-K262).
- Molecular weight context: reported MW: 43 kDa; calculated MW: nan
- Reactivity: Mouse
- Applications: ELISA, WB
As a polyclonal antibody, the reagent recognizes multiple epitopes on the target, which can improve detection robustness but may increase sensitivity to sample-dependent epitope changes.
Biological background
chitinase 3 like 1. Chitinase-3-like protein 1 (CHI3L1), also known as 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. Functional note: Carbohydrate-binding lectin with a preference for chitin. Has no chitinase activity. May play a role in tissue remodeling and in the capacity of cells to respond to and cope with changes in their environment. Plays a role in T-helper cell type 2 (Th2) inflammatory response and IL-13-induced inflammation, regulating allergen sensitization, inflammatory cell apoptosis, dendritic cell accumulation and M2 macrophage differentiation. Facilitates invasion of pathogenic enteric bacteria into colonic mucosa and lymphoid organs. Mediates activation of AKT1 signaling pathway and subsequent IL8 production in colonic epithelial cells. Regulates antibacterial responses in lung by contributing to macrophage bacterial killing, controlling bacterial dissemination and augmenting host tolerance. Also regulates hyperoxia-induced injury, inflammation and epithelial apoptosis in lung. Reported localization: Secreted, extracellular space. Cytoplasm. Endoplasmic reticulum. Detected in bronchoalveolar lavage (BAL) fluids. Localizes mainly to endoplasmic reticulum when overexpressed in cells, with some protein also detected throughout the cytoplasm. Expression/tissue context: Detected in lung in pulmonary macrophages and alveolar type 2 cells and in bronchoalveolar lavage (BAL) fluids. Expressed in mammary tumor cells (at protein level). Expressed in lung. Not detected in non-inflammatory colon.
Research relevance and current trends
- Cytoskeleton/ECM: Researchers commonly examine how Chi3l1 relates to this theme using model systems and orthogonal readouts.
- ECM Proteins: Researchers commonly examine how Chi3l1 relates to this theme using model systems and orthogonal readouts.

Common research applications
- Western blotting: compare relative Chi3l1 levels across conditions; band patterns may reflect isoforms and processing.
- ELISA-compatible use: when applicable, interpret signal as relative abundance across sample sets with consistent handling and dilution strategy.
Notes for experimental interpretation
- Specificity notes: No cross reactivity with other proteins.
- Cross-reactivity: No cross-reactivity with other proteins.
- Isoforms and PTMs: Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.
- Controls: Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD/KO samples when available.
