Heparin-binding EGF-like growth factor (HB-EGF) is a 1216 kDa member of the epidermal growth factor (EGF) family. It possesses an EGFlike domain, and a heparin-binding motif. Mature HBEGF is a soluble peptide that arises from proteolytic processing of the transmembrane form. Human HBEGF shows 76% and 73% aa sequence identity with rat and mouse HBEGF, respectively. It is required for normal cardiac valve formation and normal heart function, promotes smooth muscle cell proliferation. It may be involved in macrophage-mediated cellular proliferation; it is mitogenic for fibroblasts, but not endothelial cells. HBEGF classified as a group 2 ErbB ligand based on its ability to activate both the EGF/ErbB1 and ErbB4 receptors. Activity associated with ErbB4 binding appears to be limited to nonmitogenic actions, while EGFR binding induces both mitogenic and nonmitogenic activity.

|
| 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 |
Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at-80℃. For reconstituted proteinsolutions, 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. Solutions are shipping with dry ice.
