Description：Recombinant Human DKK1 Protein is produced by mammalian expression system and the target gene encoding Thr32-His266 is expressed with a 8His tag at the N-terminus.Form：Lyophilized from a 0.2 μM filtered solution of PBS, pH 7.4.Gene Symbol：DKK1Alternative Names：Dickkopf-related protein 1; Dickkopf-1; Dkk-1; hDkk-1; SK Entrez Gene (Human)： 22943; SwissProt (Human)： O94907; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：HHHHHHHHQT LNSVLNSNAI KNLPPPLGGA AGHPGSAVSA APGILYPGGN KYQTIDNYQP YPCAEDEECG TDEYCASPTR GGDAGVQICL ACRKRRKRCM RHAMCCPGNY CKNGICVSSD QNHFRGEIEE TITESFGNDH STLDGYSRRT TLSSKMYHTK GQEGSVCLRS SDCASGLCCA RHFWSKICKP VLKEGQVCTK HRRKGSHGLE IFQRCYCGEG LSCRIQKDHH QASNSSRLHT CQRHDirections 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.
