Product Overview | |
| Name | ECGS Bovine |
|---|---|
| Description | |
| Endothelial Mitogen Bovine | |
| Synonyms | |
| EDN2, EDN-2, vasoactive intestinal contractor peptide, VIC, ET-2, Endothelin-2, Preproendothelin-2, PPET2, ET2. | |
| Introduction | |
| Endothelin-2 is a Hypoxia-induced Autocrine Survival Factor for Breast Tumor Cells. The synthesis of EDN2 by human kidney carcinoma cells is decreased by EGF. EDN2 is a chemoattractant for macrophages and THP-1 monocytic cells. Chemotaxis towards EDN2 is via the MAPK pathway: p44 and p42 are phosphorylated when THP-1 cells are stimulated with EDN2. Migration to EDN2 is inhibited by hypoxia and by pertussis toxin. EDN2 leads to activation of macrophages. EDN2 shares a similar peptide sequence with chemokines and may signal via a similar receptor and MAPK-mediated pathway. Furthermore, EDN2 expression by tumors may modulate the behavior of macrophages such that activated cells accumulate in areas of hypoxia. | |
| Physical Appearance | |
| Sterile Filtered White lyophilized (freeze-dried) powder. | |
| Formulation | |
| The protein (1mg/ml) was lyophilized with no additives. | |
| Stability | |
| Lyophilized EDN2 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution EDN2 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. | |
| Purity | |
| Greater than 95.0% as determined by RP-HPLC. | |
| Amino acid sequence | |
| Cys-Ser-Cys-Ser-Ser-Trp-Leu-Asp-Lys-Glu-Cys-Val-Tyr-Phe-Cys-His-Leu-Asp-Ile-Ile-Trp. | |
| Solubility | |
| It is recommended to reconstitute the lyophilized EDN2 in sterile 18MΩ-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions. | |
| Precautions | |
| ECGS Bovine is for research use only and not for use in diagnostic or therapeutic procedures. | |
