Catalog Number: C22-601-14                                                                                                       Source:Escherichia coli 

Molecular Weight: Approximately 6.7 kDa, containing 60 amino acids, which includes a 40-amino acid trefoil motif
containing three conserved intramolecular disulfide bonds.
Quantity:5μg/20μg/1000μg
AA Sequence: EAQTETCTVA PRERQNCGFP GVTPSQCANK GCCFDDTVRG VPWCFYPNTI DVPPEEECEF
Purity:>97% by SDS-PAGE and HPLC analyses.
Biological Activity: Fully biologically active when compared to standard. The ED50 determined by a chemotaxis bioassay
using human MCF-7 cells is less than 10000 ng/ml, corresponding to a specific activity of ＞ 1.0 ×10^2IU/mg.
Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation: Lyophilized from a 0.2μm filtered concentrated solution in 20mM PB, pH 7.4, 150mM NaCl.
Endotoxin: Less than 1EU/μg of rHuTFF1 as determined by LAL method.
Reconstitution: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.
Storage:  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.
