Human Cytokine/Growth Factor/Chemokines Sample Spec sheets (subject to change without notice):
DATA SHEET: :recombinant HUMAN Trefoil Factor 2 (TFF2)
-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 (
Catalog#: RDI-3059 lot#
Package Size: 20 micrograms $258.50
Mini-Pack: cat#RDI-3059p $104.50/5ug
Supplied: Lyophilized powder with no additives.
Source: E. Coli
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 DEG 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 DEG C for up to 1 week or at -20 DEG 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.
Storage: The lyophilized powder is stable at room temperature for a few weeks but it is best stored desiccated at -20 DEG C. Reconstituted TFF2 should be stored in working aliquots at -20 DEG C. AVOID FREQUENT FREEZE THAW CYCLES.
Reactivity: Determined by its ability to chemoattract human monocytes using a concentration of 1-10.0ng/ml
