Description：Recombinant Human Complement C5 Protein is produced by E.coli expression system and the target gene encoding Thr678-Arg751 is expressed.Form：Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4.Gene Symbol：C5Alternative Names：CPAMD4; Complement C5; C3 and PZP-like alpha-2-macroglobulin domain-containing protein 4 Entrez Gene (Human)： 727; SwissProt (Human)： P01031; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：STLQKKIEEI AAKYKHSVVK KCCYDGACVN NDETCEQRAA RISLGPRCIK AFTECCVVAS QLRANISHKD MQLGRDirections 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 ddH2O. 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.
