Description：Recombinant Human BDNF Protein is produced by E. coli. It is a single non-glycosylated polypeptide chain containing 119 amino acids. Bioactive BDNF is a non-covalently linked homodimer with a molecular mass of 27 kD.Form：Lyophilized from a 0.2 μM filtered solution of 20mM PB, 250mM NaCl, pH 7.2.Gene Symbol：BDNFAlternative Names：Brain-derived neurotrophic factor; BDNF; Abrineurin Entrez Gene (Human)： 627; SwissProt (Human)： P23560; Purity：Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure：MHSDPARRGE LSVCDSISEW VTAADKKTAV DMSGGTVTVL EKVPVSKGQL KQYFYETKCN PMGYTKEGCR GIDKRHWNSQ CRTTQSYVRA LTMDSKKRIG WRFIRIDTSC VCTLTIKRGRDirections for Use：Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in 1X PBS. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.Quality Control：Endotoxin: Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test.Storage/Stability：Lyophilized protein should be stored at -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at -20°C for 3 months.
