EDN2, Human

(EDN2, EDN-2, vasoactive intestinal contractor peptide, VIC, ET-2, Endothelin-2, Preproendothelin-2, PPET2, ET2.)

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.

EDN2 contains 21 amino acids having a molecular mass of 2546.97 Dalton.

Purity: Greater than 95.0% as determined by RP-HPLC.

Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.

Formulation: The protein (1mg/ml) was lyophilized with no additives.

EDN2 General Information

Amino acid sequence:
Cys-Ser-Cys-Ser-Ser-Trp-Leu-Asp-Lys-Glu-Cys-Val-Tyr-Phe-Cys-His-Leu-Asp-Ile-Ile-Trp.

Storage:
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.
