Description：Recombinant E. coli ECO Protein is produced by E. coli expression system and the target gene encoding Met1-Arg162 is expressed with a 6His tag at the C-terminus.Form：Lyophilized from a 0.2 μM filtered solution of 20mM Tris-HCl, 300mM NaCl, pH 8.5.Gene Symbol：ECOAlternative Names：eti; Ecotin Entrez Gene (Human)： 946700 (E. coli); SwissProt (Human)： P23827 (E. coli); Purity：Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure：MKTILPAVLF AAFATTSAWA AESVQPLEKI APYPQAEKGM KRQVIQLTPQ EDESTLKVEL LIGQTLEVDC NLHRLGGKLE NKTLEGWGYD YYVFDKVSSP VSTMMACPDG KKEKKFVTAY LGDAGMLRYN SKLPIVVYTP DNVDVKYRVW KAEEKIDNAV VRLEHHHHHHDirections 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.
