| Purity | Greater than 97.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. | Source | Escherichia Coli. |
| Phycical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. | Shipping Condition | Shipped at Room temp. |
| Synonyms | DTR; HEGFL; diphtheria toxin receptor; DTSF. | ||
| Amino Acid Sequence | DLEGTDLNLF KVAFSSKPQG LATPSKERNG KKKKKGKGLG KKRDPCLRKY KDYCIHGECR YLQEFRTPSC KCLPGYHGHR CHGLTL. | ||
| Solubility | It is recommended to reconstitute the lyophilized Mouse HB-EGF in sterile 18M-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions. | ||
| Stability | Lyophilized Mouse HB-EGF Recombinant although stable at room temperature for 3 weeks, should be stored desiccated below -18°C . Upon reconstitution HB-EGF should be stored at 4°C between 2-7 days and for future use below -18°C .For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles. | ||
| Biological Activity | The ED50 was determined by a cell proliferation assay using balb/c 3T3 cells is < 1.0 ng/ml, corresponding to a specific activity of > 1.0б┴106 units/mg. | ||
| Formulation | The protein was filtered (0.2µm) and lyophilized from a concentrated solution containing 10mM PB and 500mM NaCl, pH7.4. | ||
HB-EGF is an EGF related growth factor which signals via the EGF receptor, and stimulates the proliferation of SMC (smooth muscle cells), fibroblasts, epithelial cells and keratinocytes. HB-EGF is expressed in various cell types and tissues, including vascular endothelial cells and SMC, macrophages, skeletal muscle, keratinocytes and particular tumor cells. HB-EGF's ability to explicitly bind sulfate proteoglycans is dissimilar from other EGF-like molecules, and might be related to the enhanced mitogenic activity, relative to EGF, that HB-EGF exerts on smooth muscle cells.
The ED50 was determined by a cell proliferation assay using balb/c 3T3 cells is < 1.0 ng/ml, corresponding to a specific activity of > 1.0б┴106 units/mg.
