  • Background
    • Background

      Galectin-2 (Gal-2) is a lectin family member and structurally closely related to galectin-1. It contains one carbohydrate recognition domain (CRD), responsible for β-galactoside binding, and is biologically active as homodimers. Galectin-2 serves as a proapoptotic effector for activated T cells through caspase-3 signaling. Moreover, galectin-2 has emerged as a crucial factor in driving the macrophage to CD40-positive M1 polarization, leading to arteriogenesis attenuation and collateral arteries remodeling.

  • 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.


      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.
