  • Background
    • Background

      Chitinases and non-enzymatic chitinase-like proteins (CLPs, can bind chitin but cannot digest) belong to Glycoside hydrolase family 18. Human CHI3L1, YKL-40, is a CLP and a 42 kDa protein with 383 amino acid residues. The complex (CHI3L1, IL-13R alpha2 and IL-13) regulate downstream signal transduction pathway related to inflammation, proliferation and metastasis.

  • Instruction
    • Reconstitution

      It is recommended to reconstitute the lyophilized protein in sterile H₂O to a concentration not less than 200 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.

      Shipping

      The product is shipped with polar packs. Upon receipt, store it immediately at -20°C or lower for long term storage.

    • Stability & Storage

      This product is stable after storage at:

      • -20°C for 12 months in lyophilized state from date of receipt.
      • -20°C or -80°C for 1 month under sterile conditions after reconstitution.

      Avoid repeated freeze/thaw cycles.
