Description：Recombinant Human QDPR Protein is produced by mammalian expression system and the target gene encoding Ala2-Phe244 is expressed with a 6His tag at the C-terminus.Form：Lyophilized from a 0.2 μM filtered solution of 20mM Tris-HCl, pH 8.0.Gene Symbol：QDPRAlternative Names：DHPR; Dihydropteridine reductase; HDHPR; Quinoid dihydropteridine reductase Entrez Gene (Human)： 5860; SwissProt (Human)： P09417; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：AAAAAAGEAR RVLVYGGRGA LGSRCVQAFR ARNWWVASVD VVENEEASAS IIVKMTDSFT EQADQVTAEV GKLLGEEKVD AILCVAGGWA GGNAKSKSLF KNCDLMWKQS IWTSTISSHL ATKHLKEGGL LTLAGAKAAL DGTPGMIGYG MAKGAVHQLC QSLAGKNSGM PPGAAAIAVL PVTLDTPMNR KSMPEADFSS WTPLEFLVET FHDWITGKNR PSSGSLIQVV TTEGRTELTP AYFVDHHHHH HDirections 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.
