• About recombinant protein
  The Trefoil Factor peptides (TFF1, TFF2 and TFF3) are expressed in the gastrointestinal tract, and appear to play an important role in intestinal mucosal defense and repair. TFF1 is essential for normal differentiation of the antral and pyloric gastric mucosa and functions as a gastric-specific tumor suppressor gene. Recombinant human TFF1 is a 6.7 kDa monomeric protein consisting of a 60 amino acid polypeptide chain, which includes a 40-amino acid trefoil motif containing three conserved intramolecular disulfide bonds.

• Activity
  Biological activity was determined by its ability to chemoattract human MCF - 7 cells using a concentration 5 - 10 μg/mL.
• Keep at
  The lyophilized Trefoil Factor 1 recombinant protein is stable for at least 2 years from date of receipt at -20˚C. Reconstituted Trefoil Factor 1 is stable for at least 3 months when stored in working aliquots with a carrier protein at -20˚C. As with any protein, exposing Trefoil Factor 1 recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.

• Description
  Aplha, transcription related growth factors and stimulating factors or repressing nuclear factors are complex subunits of proteins involved in cell differentiation. Complex subunit associated factors are involved in hybridoma growth, Eosinohils, eritroid proliferation and derived from promotor binding stimulating subunits on the DNA binding complex. NFKB 105 subunit for example is a polypetide gene enhancer of genes in B cells.
