分子别名(Synonym)

EFNB1,EFL-3,ELK ligand,ELK-L,EPLG2,LERK2,CFND,CFNS

表达区间及表达系统(Source)

Human Ephrin-B1, His Tag (EF1-H5223) is expressed from human 293 cells (HEK293). It contains AA Leu 28 - Gly 232 (Accession # NP_004420).

Predicted N-terminus: Leu 28

蛋白结构(Molecular Characterization)

Online(Leu 28 - Gly 232) NP_004420

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 23.6 kDa. The protein migrates as 32-40 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

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 PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

电泳(SDS-PAGE)

Human Ephrin-B1, His Tag (Cat. No. EF1-H5223) SDS-PAGE gel

Human Ephrin-B1, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.

背景(Background)

Ephrin-B1 (EFNB1) is also known as EFL-3, ELK ligand, EPH-related receptor tyrosine kinase ligand 2 (LERK-2), which belongs to the ephrin family. EFNB1 contains one ephrin RBD (ephrin receptor-binding) domain. EFNB1 binds to the receptor tyrosine kinases EPHB1 and EPHA1. EFNB1 binds to, and induce the collapse of, commissural axons/growth cones in vitro. EFNB1 may play a role in constraining the orientation of longitudinally projecting axons. EFNB1 interacts with GRIP1 and GRIP2.
