Ephrin-B2/EFNB2 Protein, Mouse (HEK293, Fc-His)

Ephrin-B2/EFNB2 Protein is a transmembrane ligand for Eph receptors, mediating bidirectional signaling and binding to EPHA4, EPHA3, and EPHB4. It regulates cell adhesion, migration, heart morphogenesis, angiogenesis, and axon orientation. It also interacts with PDZRN3. Ephrin-B2/EFNB2 Protein, Mouse (HEK293, Fc-His) is the recombinant mouse-derived Ephrin-B2/EFNB2 protein, expressed by HEK293 , with C-hFc, C-6*His labeled tag.

Ephrin-B2/EFNB2 Protein is a cell surface transmembrane ligand for Eph receptors, a family of receptor tyrosine kinases that play crucial roles in neuronal, vascular, and epithelial development. It binds to neighboring cells' Eph receptors, leading to contact-dependent bidirectional signaling. This interaction triggers forward signaling downstream of the receptor and reverse signaling downstream of the ephrin ligand. Ephrin-B2/EFNB2 binds promiscuously to receptor tyrosine kinases such as EPHA4, EPHA3, and EPHB4. It cooperates with EPHB4 to regulate cell adhesion, migration, heart morphogenesis, and angiogenesis. Additionally, it participates in guiding the orientation of longitudinally projecting axons and interacts with PDZRN3 (By similarity).

Measured by its binding ability in a functional ELISA. Immobilized Recombinant Mouse Ephrin B2 Protein at 2 μg/mL (100 μL/well) can bind Mouse EphB4 Protein. The ED₅₀ for this effect is 10.87 ng/mL.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US;may vary elsewhere.
