Recombinant Human Trefoil Factor 2

• Cat.No.: TFF2-659H
• Product Overview: Recombinant human TFF2 is a 12.0 kDa polypeptide of 106 amino acid residues, which includes a 40-amino acid trefoil motif containing three conserved intramolecular disulfide bonds. It was expressed inE. Coli.

Specification

• Cat. No.: TFF2-659H
• 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. TFF2 has been shown to inhibit gastrointestinal motility and gastric acid secretion. Recent data suggests a potential role for TFF2 in acute and chronic asthma.
• Source: Escherichia Coli.
• Amino Acid Sequence: EKPSPCQCSR LSPHNRTNCG FPGITSDQCF DNGCCFDSSVTGVPWCFHPL PKQESDQCVM EVSDRRNCGY PGISPEECASRKCCFSNFIF EVPWCFFPKS VEDCHY.
• Supplied: Lyophilized powder with no additives.
• Purity: >98% by SDS-Page and HPLC analysis. Endotoxin level is less than 0.1ng per ug (1EU/ug) of protein.
• Reconstitution: Lyophilized TFF2 should be reconstituted in water to a concentration of 0.1-1mg/ml. Allow to set at least 30 minutes at 4°C, mix well. If desired, tighten cap and centrifuge for 1 minute at 1000rpm to concentrate material in vial. This solution can be diluted into other buffered solutions or stored at 4°C for up to 1 week or at -20°C for future use.
• Note: If this material is not to be used for coating or labeling (or other applications requiring carrier free material), the addition of 0.1% BSA or HSA to any further dilution buffers or dilution in sterile culture media is recommended to enhance stability and minimize absorption to vial. Ideally, maintain stock >20ug/ml.
• Reactivity: Determined by its ability to chemoattract human monocytes using a concentration of 1-10.0ng/ml.
• Storage: The lyophilized powder is stable at room temperature for a few weeks but it is best stored desiccated at -20°C. Reconstituted TFF2 should be stored in working aliquots at -20°C. avoid frequent freeze thaw cycles.
• Tag: Non
