Acidic mammalian chitinase (AMCase) and chitotriosidase (CHIT-1) are two active chitinases expressed in humans. The chitinase activity of AMCase was found to be causative in allergic inflammation and its expression was found to be induced by interleukin-13. CHIT1-1 is expressed by phagocytic cells and extremely high levels are seen in lysosomal storage diseases. The expression of AMCase and CHIT-1 were differently modulated in HMMs at different stage of maturation.

| Species | Mouse |
| Expression System | HEK293 Cells |
| Tag | C-His |
| Accession Number | Q91XA9 |
| Synonyms | YNL,EC 3.2.1.14,CHIT2,Chia1,CHIA,AMCase,Acidic mammalian chitinase |
| Construction | Tyr22-Pro473 |
| Protein Purity | > 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC |
| Molecular Weight | 51 kDa (predicted). Due to glycosylation, the protein migrates to 53-60 kDa based on Tris-Bis PAGE result. |
| Endotoxin | < 1 EU/μg by the LAL method. |
| Formulation | Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization. |
| Reconstitution | Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing. |
| Stability & Storage | It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots. |
| Shipping | In general, Lyophilized powders are shipping with blue ice. |
