Description：Recombinant Human ETFB Protein is produced by E. coli expression system and the target gene encoding Met1-Ile255 is expressed with a 6His tag at the N-terminus.Form：Liquid in a 0.2 μM filtered solution of 20mM HEPES, 150mM NaCl, pH 7.4.Gene Symbol：ETFBAlternative Names：Electron transfer flavoprotein subunit beta; Beta-ETF Entrez Gene (Human)： 2109; SwissProt (Human)： P38117; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：MNHKVHHHHH HMAELRVLVA VKRVIDYAVK IRVKPDRTGV VTDGVKHSMN PFCEIAVEEA VRLKEKKLVK EVIAVSCGPA QCQETIRTAL AMGADRGIHV EVPPAEAERL GPLQVARVLA KLAEKEKVDL VLLGKQAIDD DCNQTGQMTA GFLDWPQGTF ASQVTLEGDK LKVEREIDGG LETLRLKLPA VVTADLRLNE PRYATLPNIM KAKKKKIEVI KPGDLGVDLT SKLSVISVED PPQRTAGVKV ETTEDLVAKL KEIGRIDirections 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：Store it at -20°C to -80°C for one year. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
