Background

CHI3L1 Protein is a carbohydrate-binding lectin that exhibits a specific preference for chitin. Although it lacks chitinase activity, it plays crucial roles in tissue remodeling and enables cells to adapt and respond to environmental changes. It is involved in various processes, such as T-helper cell type 2 (Th2) inflammatory response, IL-13-induced inflammation, regulation of allergen sensitization, modulation of inflammatory cell apoptosis, dendritic cell accumulation, and promotion of M2 macrophage differentiation. Furthermore, it facilitates the invasion of pathogenic enteric bacteria into the colonic mucosa and lymphoid organs. In colonic epithelial cells, it mediates the activation of the AKT1 signaling pathway, leading to subsequent production of IL8. CHI3L1 also regulates antibacterial responses in the lung by enhancing macrophage bacterial killing, controlling bacterial dissemination, and promoting host tolerance. Additionally, it plays a role in regulating hyperoxia-induced injury, inflammation, and epithelial apoptosis in the lung. It exists as a monomer.

Biological Activity

Measured by the ability of the immobilized protein to support the adhesion of FaDu human squamous cell carcinoma cells. The ED50 for this effect is 3.232 μg/ml, corresponding to a specific activity is 309.4059 units/mg.

Molecular Weight

Approximately 40.83 kDa

Purity
  • Greater than 95% as determined by reducing SDS-PAGE
Appearance

Lyophilized powder.

Formulation

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4 or 20 mM PB, 150 mM NaCl, pH 7.4.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping

Room temperature in continental US; may vary elsewhere.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
