- SynonymCHI3L1,YKL-40,CGP-39,GP-39,ASRT7
- SourceHuman CHI3L1, His Tag (CH1-H5228) is expressed from human 293 cells (HEK293). It contains AA Tyr 22 - Thr 383 (Accession # AAH38354).Predicted N-terminus: Tyr 22Request for sequence
- Molecular Characterization
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 41.2 kDa. The protein migrates as 40-45 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
- EndotoxinLess than 1.0 EU per μg by the LAL method.
- Purity
>95% as determined by SDS-PAGE.
- Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

- BackgroundChitinase-3-like protein 1 (CHI3L1) is also known as Cartilage glycoprotein 39 (CGP-39), YKL-40, which belongs to the glycosyl hydrolase 18 family. CHI3L1 is present in activated macrophages, articular chondrocytes, synovial cells as well as in liver. CHI3L1 may play a role in defense against pathogens, or in tissue remodeling and also may play an important role in the capacity of cells to respond to and cope with changes in their environment.
