Recombinant Human BDNF Protein
Growth factors from Cell Guidance Systems are high purity suitable for the most demanding applications where biological activity is required.
Aliases
brain-derived neurotrophic factor, neurotrophin, abrineurin, Abrineurin
Description:
BDNF is a member of the nerve growth factor family of trophic factors. In the brain BDNF has a trophic action on retinal, cholinergic, and dopaminergic neurons, and in the peripheral nervous system it acts on both motor and sensory neurons. Some protein domains of BDNF are identical with those of NGF and another neurotrophic factor, designated NT-3 (neurotrophin-3). Polyclonal antibodies raised against murine NGF have been shown to cross-react with both NT-3 and BDNF. Recombinant Human Brain-Derived Neurotrophic Factor produced in E.coli is a homodimer, non-glycosylated, polypeptide chain containing 2 x 119 amino acids and having a total molecular mass of 26,984 Dalton
Physical Appearance:
Sterile Filtered white lyophilized (freeze-dried) powder.
Source:
E.coli
Formulation:
Lyophilized with no additives.
Reconstitution:
Centrifuge vial before opening. When reconstituting the product, gently pipet and wash down the sides of the vial to ensure full recovery of the protein into solution. It is recommended to reconstitute the lyophilized product with sterile water at a concentration of 0.1 mg/ml, which can be further diluted into other aqueous solutions.
Stability:
Lyophilized product is very stable at -20°C. Reconstituted material should be aliquoted and frozen at -20°C. It is recommended to add a carrier protein (0.1% HSA or BSA) for long term storage.
Purity Greater than 97% as determined by:
Analysis by RP-HPLC.
Reducing and non-reducing SDS-PAGE.
Protein Content determined by:
UV spectroscopy at 280 nm.
Analysis by RP-HPLC calibrated against a known standard.
Quantitation on SDS-PAGE against a known standard.
Endotoxin Level:
Endotoxin level as measured by LAL is <0.01ng/ug or <0.1EU/ug.
Biological Activity:
BDNF is fully biologically active when compared to standard. The ED50, as calculated via the dose-dependent induction of rat C6 glioma cell proliferation, is 1ug/ml.
