  • Cat.No.
  • CSC-CTK0421
  • Description
  • 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 13.2 kDa homodimeric protein consisting of two 60 amino acid polypeptide chains, which includes a 40-amino acid trefoil motif containing three conserved intramolecular disulfide bonds.
  • Species
  • Human

  • Expression System
  • E.coli
  • Purity
  • Greater than 98% as determined by HPLC and SDS-PAGE analysis.
  • Activity
  • Determined by its ability to activate ERK1/2 (a MAPkinase signaling molecule) using a concentration 1.0-2.0 μg/ml.
  • Endotoxin Level
  • Less than 1 EU/μg.
  • Formulation
  • Lyophilized
  • Reconstitution
  • Please centrifuge product briefly before opening vial. The lyophilized protein should be reconstituted in sterile, ultra-pure water to a concentration of 0.1-1.0 mg/ml. This solution can then be diluted into other aqueous buffers and stored at -20°C for future use.
  • Storage & Stability
  • The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted protein should be used immediately or stored long-term in undiluted working aliquots at -20°C. Avoid repeated freeze-thaw cycles.
