Introduction
Trefoil Factor 2 (TFF2) is a member of the trefoil family and contains two P-type (trefoil) domains. Members of this family are characterized by having at least one copy of the trefoil motif, a 40-amino acid domain that contains three conserved disulfides. TFF2 is a secreted protein and specifically expressed in the stomach. TFF2 inhibits gastrointestinal motility and gastric acid secretion. TFF2 could function as a structural component of gastric mucus, possibly by stabilizing glycoproteins in the mucus gel through interactions with carbohydrate side chains.
BP000121-CYT-612: Recombinant Human Trefoil Factor 2 (TFF2) Protein
Source: E. coli-derived.
A single, non-glycosylated, polypeptide chain containing 106 amino acids (24-129) and having a total molecular mass of 12 kDa.
Determined by its ability to chemoattract human MCF-7 cells using a concentration 1.0-10.0 ug/ml.
Purity: > 97% by SDS-PAGE and RP-HPLC.
Formulation: Lyophilized from 0.4 ?m filtered solution at a concentration of 1 ug/ml containing 1x PBS pH-7.4.
Reconstitution: It is recommended to reconstitute the lyophilized TFF2 in sterile 18 M?-cm H2O not less than 100 ug/ml, which can then be further diluted to other aqueous solutions.
Shipping: The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature recommended below.
Stability & Storage: Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
12 months from date of receipt, -20 to -70°C as supplied.
1 month, 2 to 8°C under sterile conditions after reconstitution.
3 months, -20 to -70°C under sterile conditions after reconstitution.
