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.

Recombinant 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.

Molecular Characterization
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 23.2 kDa. The protein migrates as 32-40 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Less than 1.0 EU per μg by the LAL method.

>95% as determined by SDS-PAGE.

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally Mannitol or Trehalose are added as protectants before lyophilization.

See Certificate of Analysis for reconstitution instructions and specific concentrations.

Avoid repeated freeze-thaw cycles.
No activity loss was observed after storage at:
In lyophilized state for 1 year (4°C); After reconstitution under sterile conditions for 3 months (-70°C).
