Brain-Derived Neurotrophic Factor Human Recombinant, BDNF Human, 10ug

Amino acid sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Met-His-Ser-Asp-Pro.

Biological Activity
The ED50, calculated by the dose-dependant induction of ACHE (acetylcholine esterase) in rat basal forebrain primary septal culture is 50 ng/ml corresponding to a Specific Activity of 20,000IU/mg.

Description
Brain-Derived Neurotrophic Factor Human Recombinant 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.
BDNF Human Recombinant is purified by proprietary chromatographic techniques.

Formulation
The protein was lyophilized after dialysis against 20mM sodium citrate buffer pH=5.

Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.

Protein content
BDNF quantitation was carried out by two independent methods
1. UV spectroscopy at 280 nm using the absorbency value of 1.6 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).

2. Analysis by RP-HPLC, using a standard solution of Brain-derived Neurotrophic Factor as a Reference Standard.

Purity
Greater than 96.0% as determined by(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Solubility
It is recommended to reconstitute the lyophilized Brain-derived Neurotrophic Factor in sterile 18M¦¸-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Source
Escherichia Coli.

Stability
Lyophilized BDNF although stable at room temperature for 3 weeks, should be stored desiccated below -18¡ãC. Upon reconstitution Brain-derived Neurotrophic Factor should be stored at 4¡ãC between 2-7 days and for future use below -18¡ãC.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.

Synonyms
BDNF, MGC34632.
