| Scientific Background | Breast cancer (BC) is the most common cancer in women and the second leading cause of their cancer death. Establishing an accurate BC prognosis is very difficult because of its heterogeneity. Elevated TFF1 levels in serum were associated with development of BC, TFF1 expression was upregulated in BC compared to the healthy breast tissue.That expression of TFF1 was related to ER status of BC and that expression of TFF1 was lower in TNBC than in non-TNBC. |
| Molecular Mass | The protein has a predicted MW of 33.3 kDa. Due to glycosylation, the protein migrates to 40-45 kDa based on Bis-Tris PAGE result. |
| Sl Sequence | Glu25-Phe84 |
| Solubility | Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 μg or less, at 1mg/ml for 500μg or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking. |
| Appearance | Lyophilized |
| Endotoxin Levels | Less than 1 EU per μg by the LAL method. |
| Expression System | HEK293 |
| Gene Id | P04155 |
| Amino Acid Sequence | Recombinant Human TFF1 Protein is expressed from HEK293 with hFc (IgG1) tag at the C-Terminus.It contains Glu25-Phe84. |
| Storage | -20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles. |
