Description: Recombinant Human C1QTNF9 Protein is produced by mammalian expression system and the target gene encoding Gln20-Pro333 is expressed with a 6His tag at the C-terminus. Form: Lyophilized from a 0.2 μM filtered solution of PBS, pH 7.4. Gene Symbol: C1QTNF9 Alternative Names: C1QTNF9A; Complement C1q and tumor necrosis factor-related protein 9A; Complement C1q and tumor necrosis factor-related protein 9Entrez Gene (Human): 338872SwissProt (Human): P0C862Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : QDTCRQGHPG IPGNPGHNGL PGRDGRDGAK GDKGDAGEPG RPGSPGKDGT SGEKGERGAD GKVEAKGIKG DQGSRGSPGK HGPKGLAGPM GEKGLRGETG PQGQKGNKGD VGPTGPEGPR GNIGPLGPTG LPGPMGPIGK PGPKGEAGPT GPQGEPGVRG IRGWKGDRGE KGKIGETLVL PKSAFTVGLT VLSKFPSSDV PIKFDKILYN EFNHYDTAAG KFTCHIAGVY YFTYHITVFS RNVQVSLVKN GVKILHTKDA YMSSEDQASG GIVLQLKLGD EVWLQVTGGE RFNGLFADED DDTTFTGFLL FSSPVDHHHH HH 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.
