Acidic mammalian chitinase (CHIA), human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 1-368aa. Protein Length: Full Length of Isoform 2. Tag Info: N-terminal GST-tagged. Target Protein Sequence: MVSTPENRQT FITSVIKFLR QYEFDGLDFD WEYPGSRGSP PQDKHLFTVL VQEMREAFEQ EAKQINKPRL MVTAAVAAGI SNIQSGYEIP QLSQYLDYIH VMTYDLHGSW EGYTGENSPL YKYPTDTGSN AYLNVDYVMN YWKDNGAPAE KLIVGFPTYG HNFILSNPSN TGIGAPTSGA GPAGPYAKES GIWAYYEICT FLKNGATQGW DAPQEVPYAY QGNVWVGYDN IKSFDIKAQW LKHNKFGGAM VWAIDLDDFT GTFCNQGKFP LISTLKKALG LQSASCTAPA QPIEPITAAP SGSGNGSGSS SSGGSSGGSG FCAVRANGLY PVANNRNAFW HCVNGVTYQQ NCQAGLVFDT SCDCCNWA. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference. Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20 °C/-80 °C. The shelf life of lyophilized form is 12 months at -20 °C/-80 °C. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: Degrades chitin and chitotriose. May participate in the defense against nematodes, fungi and other pathogens. Plays a role in T-helper cell type 2 (Th2) immune response. Contributes to the response to IL-13 and inflammation in response to IL-13. Stimulates chemokine production by pulmonary epithelial cells. Protects lung epithelial cells against apoptosis and promotes phosphorylation of AKT1. Its function in the inflammatory response and in protecting cells against apoptosis is inhibited by allosamidin, suggesting that the function of this protein depends on carbohydrate binding.
