Source

Human Ephrin-A1, Fc Tag (EF1-H5251) is expressed from human 293 cells (HEK293). It contains AA Asp 19 - Ser 182 (Accession # P20827-1).

Predicted N-terminus: Asp 19

Molecular Characterization

This protein carries a human IgG1 Fc tag at the C-terminus.

The protein has a calculated MW of 46.0 kDa. The protein migrates as 53-57 kDa under reducing (R) condition, and 100-115 kDa under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.

Endotoxin

Less than 1.0 EU per μg by the LAL method / rFC method.

Purity

>90% as determined by SDS-PAGE.

Formulation

Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5 with trehalose as protectant.

Background Introduction

Ephrin-A1 (EFNA1) is also known as EPLG1, LERK1, TNFAIP4, Immediate early response protein B61, which belongs to the ephrin family. EFNA1 contains one ephrin RBD (ephrin receptor-binding) domain. EFNA1 is cell surface GPI-bound ligand for Eph receptors, and is a family of receptor tyrosine kinases which are crucial for migration, repulsion and adhesion during neuronal, vascular and epithelial development. EFNA1 binds promiscuously Eph receptors residing on adjacent cells, leading to contact-dependent bidirectional signaling into neighboring cells. EFNA1 plays an important role in angiogenesis and tumor neovascularization.
