Description | Recombinant of human TFF2 protein |
Form/Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
Purity | Greater than 97.0% as determined by(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. |
Solubility (25°C) | It is recommended to reconstitute the lyophilized TFF2 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. |

Source | Escherichia Coli |
Biological Activity | Determined by its ability to chemoattract human MCF-7 cells using a concentration 1.0-10.0 ng/ml. |
Storage | Stability: Lyophilized TFF2 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution TFF2 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 |
Buffer/Preservatives | The TFF2 protein was lyophilized from 0.4μm filtered solution at a concentration of 1mg/mL containing 1x PBS pH-7.4. |
