Recombinant Human Trefoil Factor 2 (rHu TFF-2)

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 (Nikolaidis, N.M. et al. Am. Journal Respir. Cell Mol. Biol. (2003) 4: 458-464) .

Product Specifications

Source

Escherichia coli

Endotoxin

Less than 1EU/μg of rHuTFF-2 as determined by LAL method.

Purity

>97% by SDS-PAGE and HPLC analyses.

Bioactivity

Fully biologically active when compared to standard.Determined by its ability to chemoattract human monocytes using a concentration range of 1.0-10.0 μg/ml, corresponding to a Specific Activity of >100 IU/mg.

Form

Lyophilized from a 0.2μm filtered concentrated solution in 20mM PB, pH 7.4, 130mM NaCl.

Molecular Weight

12.0 kDa, a single non-glycosylated polypeptide chain containing 106 amino acids.

Storage Conditions

This lyophilized preparation is stable at 2-8°C, but should be kept at -20°C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20°C to -70°C. Avoid repeated freeze/thaw cycles.

Notes

For research use only.

Applications Notes

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at < -20°C. Further dilutions should be made in appropriate buffered solutions.
