Shipped at 4°C. Store at +4°C short term (1-2 weeks). Upon delivery aliquot. Store at -20°C long term. Avoid freeze / thaw cycle.
pH: 7.40 Constituent: PBS
ReconstitutionReconstitute the lyophilized TFF2 in sterile 18MOhm-cm H2O not less than 100µg/ml
spasmolytic protein 1
Trefoil factor 2
trefoil factor 2 (spasmolytic protein 1)
Trefoil factor 2 precursor
FunctionInhibits gastrointestinal motility and gastric acid secretion. Could function as a structural component of gastric mucus, possibly by stabilizing glycoproteins in the mucus gel through interactions with carbohydrate side chains.
