Human TFF2 Protein
Recombinant of human TFF2 protein
Product Specifications
Product Name Alternative
TFF-2, Spasmolytic polypeptide, Spasmolysin, SML1, Trefoil factor 2, SP, TFF2.
Source
Escherichia Coli
Purity
Greater than 97.0% as determined by (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
Bioactivity
Determined by its ability to chemoattract human MCF-7 cells using a concentration 1.0-10.0 ng/ml.
Form
Sterile Filtered White lyophilized (freeze-dried) powder.
Solubility
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.
Storage Conditions
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
Notes
For research use only.
Applications Notes
Cytokines And Growth Factors
Preservative
The TFF2 protein was lyophilized from 0.4μm filtered solution at a concentration of 1mg/mL containing 1x PBS pH-7.4.
