Neuroglobin, 151 amino acid residue protein, mainly expressed in vertebrate brain and retina, is a recently identified member of the globin superfamily. Augmenting O (2) supply, neuroglobin promotes survival of neurons upon hypoxic injury, potentially limiting brain damage. Moreover, neuroglobin may be a novel oxidative stress-responsive sensor for signal transduction in the brain. Neuroglobin expression is increased by neuronal hypoxia in vitro and focal cerebral ischemia in vivo, and neuronal survival after hypoxia is reduced by inhibiting neuroglobin expression with an antisense oligodeoxynucleotide and enhanced by neuroglobin overexpression.
Neuroglobin Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 161 amino acids (1-151a.a) and having a molecular mass of 18kDa. NGB is fused to 10 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
Filtered White lyophilized (freeze-dried) powder.
NGB is Filtered (0.4μm) and lyophilized from 0.5mg/ml in phosphate buffered saline.
Greater than 90% as determined by SDS-PAGE.
It is recommended to add deionized water to prepare a working stock solution of approximately 0.5mg/ml and let the lyophilized pellet dissolve completely. Neuroglobin is not sterile! Please filter the product by an appropriate sterile filter before using it in the cell culture.
Store lyophilized protein at -20°C. Aliquot the product after reconstitution to avoid repeated freezing/thawing cycles. Reconstituted protein can be stored at 4°C for a limited period of time; it does not show any change after two weeks at 4°C.
