Description：Recombinant Human BNP Protein is produced by E.coli expression system and the target gene encoding His27-Arg102 is expressed with a 6His, Flag tag at the N-terminus.Form：Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4.Gene Symbol：NPPBAlternative Names：Natriuretic peptides B; Gamma-brain natriuretic peptide Entrez Gene (Human)： 4879; SwissProt (Human)： P16860; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：MNHKVHHHHH HMDYKDDDDK HPLGSPGSAS DLETSGLQEQ RNHLQGKLSE LQVEQTSLEP LQESPRPTGV WKSREVATEG IRGHRKMVLY TLRAPRDirections 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 ddH2O. 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.
