  • Background
    • Background

      Human Holo-Transferrin Protein is an important iron-binding protein that plays a crucial physiological role in the human body. It is primarily found in blood and bodily fluids, responsible for transporting and delivering iron to various tissues and cells. Transferrin consists of two identical subunits, each capable of binding two iron ions. In the bloodstream, Transferrin transports iron from iron storage sites such as the intestines, liver, and spleen to other tissues to meet the cellular demand for iron.

  • Instruction
    • Reconstitution

      It is recommended to reconstitute the lyophilized protein in sterile H₂O to a concentration not less than 2 mg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.
      After filtration, the solution can be stored under sterile conditions at 2-8°C for 30 days.


      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.
      • 4°C for 1 month under sterile conditions after reconstitution.

      Avoid repeated freeze/thaw cycles.
