Human TFF3 Recombinant
$60.00 – $2,500.00
| accession | Q07654 |
| Source | Optimized DNA sequence encoding Human TFF3 mature chain was expressed in ECOLI. Recombinant Human Trefoil factor 3 encodes amino acid residues 36-94. |
| Molecular weight | Recombinant TFF3 migrates as an approximately 6 kDa protein under reducing conditions in SDS-PAGE. |
| Purity | >95%, as determined by SDS-PAGE and HPLC |
| Biological Activity | Determined by its ability to chemoattract human MCF-7 cells using a concentration range of 1.0-10.0 μg/ml. |
| Endotoxin | Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg). |
| Presentation | TFF3 was Lyophilized from PBS, pH 7.2. |
| Sequence | EEYVGLSANQ CAVPAKDRVD CGYPHVTPKE CNNRGCCFDS RIPGVPWCFK PLQEAECTF |
| Reconstitution | A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers. |
| Storage | The lyophilized protein is stable for at least 2 years from date of receipt at -20° C. Upon reconstitution, this product can be stored in working aliquots at 2° - 8° C for one month, or at -20° C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles. |
