Description：Recombinant Human PPY Protein is produced by mammalian expression system and the target gene encoding Ala30-Arg88 is expressed with a 6His tag at the C-terminus.Form：Lyophilized from a 0.2 μM filtered solution of 20mM PB, 150mM NaCl, pH 7.4.Gene Symbol：PPYAlternative Names：PNP; Pancreatic prohormone; Pancreatic polypeptide; PP; Obinepitide Entrez Gene (Human)： 5539; SwissProt (Human)： P01298; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：APLEPVYPGD NATPEQMAQY AADLRRYINM LTRPRYGKRH KEDTLAFSEW GSPHAAVPRV DHHHHHHDirections 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.
