SPECIFICATIONS
HostMammalian Cells
ConjugationUnconjugated
ImmunogenHomo sapiens (Human)
General Information
| Short Description | Recombinant-Active-Human EFNA1-C-His protein was developed from mammalian cells and has a target region of C-His. For use in research applications. |
| Applications | ELISA/WB |
| Host | Mammalian Cells |
| Note | STRICTLY FOR FURTHER SCIENTIFIC RESEARCH USE ONLY (RUO). MUST NOT BE USED IN DIAGNOSTIC OR THERAPEUTIC APPLICATIONS. |
Product Properties
| Conjugation | Unconjugated |
| Dilution Range | Reconstitute in sterile water for a stock solution. |
| Formulation | Lyophilized from a solution in PBS pH 7.4, 5% Trehalose, 5% Mannitol. |
| Storage Instruction | Use a manual defrost freezer and avoid repeated freeze thaw cycles. Store at 2 to 8°C for one week. Store at-20 to-80°C for twelve months from the date of receipt. |
| Endotoxin | <0.1 EU/Mu g of the protein by the LAL method. |
| Immunoreactivity | Measured by its binding ability in a functional ELISA. When recombinant human (rh) EphA2 is coated at 2 Mu g/mL (100 Mu L/well) , the concentration of rhEFNA1 that produces 50% of the optimal binding response is found to be approximately 0.6-3 ng/mL. |

Additional Info
| Post Translational Modifications | Undergoes proteolysis by a metalloprotease to give rise to a soluble monomeric form. N-Glycosylation is required for binding to EPHA2 receptor and inducing its internalization. |
| Function | Cell surface GPI-bound ligand for Eph receptors, a family of receptor tyrosine kinases which are crucial for migration, repulsion and adhesion during neuronal, vascular and epithelial development. Binds promiscuously Eph receptors residing on adjacent cells, leading to contact-dependent bidirectional signaling into neighboring cells. Plays an important role in angiogenesis and tumor neovascularization. The recruitment of VAV2, VAV3 and PI3-kinase p85 subunit by phosphorylated EPHA2 is critical for EFNA1-induced RAC1 GTPase activation and vascular endothelial cell migration and assembly. Exerts anti-oncogenic effects in tumor cells through activation and down-regulation of EPHA2. Activates EPHA2 by inducing tyrosine phosphorylation which leads to its internalization and degradation. Acts as a negative regulator in the tumorigenesis of gliomas by down-regulating EPHA2 and FAK. Can evoke collapse of embryonic neuronal growth cone and regulates dendritic spine morphogenesis. |
