商品介绍

Catalogue number

PRO-209

Synonyms

Translation initiation factor eIF-2B subunit alpha, eIF-2B GDP-GTP exchange factor subunit alpha, EIF2B1, EIF2BA, EIF2B.

Introduction

EIF2B1 is one of five subunits of eukaryotic translation initiation factor 2B (EIF2B), which is a GTP exchange factor for eukaryotic initiation factor 2 and an essential regulator for protein synthesis. Phosphorylation of eIF2 inhibits GEF activity of EIF2B, an inhibition which requires the eIF2B1 subunit. Defects in eIF2B1 are a cause of leukoencephalopathy with vanishing white matter (VWM), a brain disease which is characterized by head trauma and motor deterioration.

Description

EIF2B1 produced in E.Coli is a single, non-glycosylated polypeptide chain containing 325 amino acids (1-305 a.a.) and having a molecular mass of 35.8kDa.
EIF2B1 is fused to a 20 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.

Source

Escherichia Coli.

Physical Appearance

Sterile Filtered colorless solution.

Formulation

The EIF2B1 solution (0.5 mg/ml) contains 20mM Tris-HCl buffer (pH8.0), 10% glycerol and 0.1M NaCl.

Stability

Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.

Purity

Greater than 90.0% as determined by SDS-PAGE.
