TFF2 Human

Trefoil Factor-2 Human Recombinant

TFF-2 Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 106 amino acids (24-129) and having a total molecular mass of 12 kDa. TFF2 Human Recombinant includes a 40-amino acid trefoil motif containing three conserved intramolecular disulfide bonds and was purified by proprietary chromatographic techniques.

Biological Activity

Determined by its ability to chemoattract human MCF-7 cells using a concentration 1.0-10.0 ng/ml.

Accession

Q03403

Amino acid sequence

EKPSPCQCSR LSPHNRTNCG FPGITSDQCF DNGCCFDSSV TGVPWCFHPL PKQESDQCVM EVSDRRNCGY PGISPEECAS RKCCFSNFIF EVPWCFFPKSVEDCHY.

Formulation

The TFF2 protein was lyophilized from 0.4um filtered solution at a concentration of 1mg/mL containing 1x PBS pH-7.4.

Physical 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

It is recommended to reconstitute the lyophilized TFF2 in sterile 18MΩ-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Source

Escherichia Coli.

Stability

Lyophilized TFF2 although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution TFF2 should be stored at 4oC between 2-7 days and for future use below
-18oC.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
