Trefoil Factor-1 Human Recombinant, His Tag

TFF-1 Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 70 amino acids (25-84) which includes a 10 amino acid His Tag and having a total molecular mass of 7.9 kDa.
TFF-1 Human Recombinant is purified by proprietary chromatographic techniques.

Accession

P04155

Amino acid sequence

MKHHHHHHAS EAQTETCTVA PRERQNCGFP GVTPSQCANK GCCFDDTVRG VPWCFYPNTI DVPPEEECEF.

Formulation

The TFF1 His Tag protein was lyophilized from 0.4um filtered solution at a concentration of 0.5mg/ml containing 20mM Tris pH-7.5 and 20mM NaCl.

Physical Appearance

Filtered White lyophilized (freeze-dried) powder.

Purity

Greater than 95.0% as determined by SDS-PAGE.

Solubility

It is recommended to add deionized water to prepare a working stock solution of approximately 0.5mg/ml and let the lyophilized pellet dissolve completely. Product is not sterile! Please filter the product by an appropriate sterile filter before using it in the cell culture.

Source

Escherichia Coli.

Stability

Lyophilized TFF1 His Tag although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution TFF1 His Tag 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.
