Description: Recombinant Human NPPB Protein is produced by E. coli expression system and the target gene encoding His27-His134 is expressed with a 6His tag at the N-terminus. Form: Liquid in a 0.2 μM filtered solution of 20mM PB, 150mM NaCl, 1mM EDTA, 1mM DTT, 20% Glycerol, pH 7.4 Gene Symbol: NPPB Alternative Names: Natriuretic peptides B; Gamma-brain natriuretic peptideEntrez Gene (Human): 4879SwissProt (Human): P16860Purity : Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure : MGSSHHHHHH SSGLVPRGSH MHPLGSPGSA SDLETSGLQE QRNHLQGKLS ELQVEQTSLE PLQESPRPTG VWKSREVATE GIRGHRKMVL YTLRAPRSPK MVQGSGCFGR KMDRISSSSG LGCKVLRRH Directions 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 : Store it at -20°C to -80°C for one year. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
