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. TFF1 Protein, Mouse, Recombinant (hFc) is expressed in HEK293 mammalian cells with C-hFc tag. The predicted molecular weight is 34 kDa and the accession number is Q08423.

Species | Mouse |
Expression System | HEK293 Cells |
Tag | C-hFc |
Accession Number | Q08423 |
Synonyms | Trefoil factor 1,TFF1,PS2,Polypeptide P1.A,pNR-2,HPS2,HP1.A,D21S21,BCEI |
Construction | Gln22-Phe87 |
Protein Purity | > 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC |
Molecular Weight | 34 kDa (predicted). Due to glycosylation, the protein migrates to 38-42 kDa based on Tris-Bis PAGE result. |
Endotoxin | < 1 EU/μg by the LAL method. |
Formulation | Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization. |
Reconstitution | Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing. |
Stability & Storage | It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots. |
Shipping | In general, Lyophilized powders are shipping with blue ice. |
