Product Overview
| Tag | His |
| Host Species | Mouse |
| Accession | NP_034238.1 |
| Synonym | AW494418, EFL-2, Ehk1-L, Epl3, LERK-3 |
| Background | Ephrin-A3 also known as EPH-related receptor tyrosine kinase ligand 3 or EFNA3, is a member of the ephrin family. The Eph family receptor interacting proteins (ephrins) are a family of proteins that serve as the ligands of the Eph receptor, which compose the largest known subfamily of receptor protein-tyrosine kinases (RTKs). Ephrin-A3 and their Eph family of receptor tyrosine kinases are expressed by cells of the SVZ. Ephrin subclasses are further distinguished by their mode of attachment to the plasma membrane: Ephrin-A3 ligands bind EphA receptors and are anchored to the plasma membrane via a glycosylphosphatidylinositol (GPI) linkage, whereas ephrin-B ligands bind EphB receptors and are anchored via a transmembrane domain. Ephrin-A3 expressed on astrocytes activates EphA4 on the post-synaptic neuron and restricts the growth of dendritic spines through multiple pathways. |
| Description | A DNA sequence encoding the mouse EFNA3 (NP_034238.1) without the pro peptide (Met 1-Ser 205) was expressed, with a His tag at the C-terminus. |
| Source | HEK293 |
| Predicted N Terminal | Gln 23 |
| AA Sequence | Met 1-Ser 205 |
| Molecular Weight | The recombinant mouse EFNA3 consists of 194 a.a. and has a predicted molecular mass of 22.2 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rmEFNA3 is approximately 38 kDa due to glycosylation. |
| Purity | >92% as determined by SDS-PAGE |
| Endotoxin | < 1.0 EU per μg of the protein as determined by the LAL method |
| Bioactivity | Measured by its binding ability in a functional ELISA. Immobilized mouse EphrinA3 at 1 ug/ml (100 ul/well) can bind mouse EPHA6 with a linear ranger of 6.25-400 ng/ml. |
| Formulation | Lyophilized from sterile PBS, pH 7.4. |
| Stability | The recombinant proteins are stable for up to 1 year from date of receipt at -70°C. |
| Usage | For Research Use Only |
| Storage | Store the protein under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. |
