分子别名(Synonym)

EFNA1,Ephrin-A1,LERK-1,TNFAIP4,EPLG1,B61,ECKLG,EFL1

表达区间及表达系统(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

蛋白结构(Molecular Characterization)

Online(Asp 19 - Ser 182) P20827-1

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

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

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>95% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5. Normally trehalose is added as protectant before lyophilization.

电泳(SDS-PAGE)

Human Ephrin-A1, Fc Tag (Cat. No. EF1-H5251) SDS-PAGE gel

Human Ephrin-A1, Fc Tag on SDS-PAGE under reducing (R) and non-reducing (NR) conditions. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.

背景(Background)

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.
