Description：Recombinant Human CRP Protein is produced by E.coli expression system and the target gene encoding Gln19-Pro224 is expressed with a 6His tag at the C-terminus.Form：Lyophilized from a 0.2 μM filtered solution of 50mM Tris, 200mM Imidazole, 2M Urea, pH 8.5.Gene Symbol：CRPAlternative Names：PTX1; C-reactive protein Entrez Gene (Human)： 1401; SwissProt (Human)： P02741; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：MQTDMSRKAF VFPKESDTSY VSLKAPLTKP LKAFTVCLHF YTELSSTRGY SIFSYATKRQ DNEILIFWSK DIGYSFTVGG SEILFEVPEV TVAPVHICTS WESASGIVEF WVDGKPRVRK SLKKGYTVGA EASIILGQEQ DSFGGNFEGS QSLVGDIGNV NMWDFVLSPD EINTIYLGGP FSPNVLNWRA LKYEVQGEVF TKPQLWPLEH HHHHHDirections 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.
