Description: Recombinant Human Transferrin produced in Plant is a non-glycosylated, polypeptide chain containing 679 amino acids and having a molecular mass of 76 kDa. The Recombinant Human Transferrin is purified by proprietary chromatographic techniques.
Protein Derived From: Oryza sativa (rice).
Physical Appearance: Sterile Filtered lyophilized (freeze-dried) powder.
Purity: Purity as determined by SDS-PAGE is 97%.
Stability: Lyophilized Transferrin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Transferrin Human Recombinant should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.
Biological Activity: One mg of Recombinant Human Transferrin will bind to approximately 2 micrograms of Fe.
Solubility: Stock solutions can be prepared by dissolving gently into PBS for several minutes. Recommended stock concentrations are 5mg/ml to 20 mg/ml in PBS, though others can be used as well. Please try to avoid the formation of bubbles when dissolving the protein. Sterile filter through 0.2µm filter.
Iron Content: The average amount of Ferric Iron in our Transferrin is 0.4-0.5ug per mg of protein (protein concentration is measured by absorption at 280 nm).
