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: CRP Alternative Names: PTX1; C-reactive proteinEntrez Gene (Human): 1401SwissProt (Human): P02741Purity : 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 HHHHH Directions 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.
