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: ETFB Alternative Names: Electron transfer flavoprotein subunit beta; Beta-ETFEntrez Gene (Human): 2109SwissProt (Human): P38117Purity : 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 KEIGRI 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 : 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.
