Description: Recombinant Human EIF1B Protein is produced by E.coli expression system and the target gene encoding Met1-Phe113 is expressed with a 6His tag at the N-terminus. Form: Lyophilized from a 0.2 μM filtered solution of 20mM Tris-HCl, 500mM NaCl, pH 8.0. Gene Symbol: EIF1B Alternative Names: Eukaryotic translation initiation factor 1b; eIF1b; Protein translation factor SUI1 homolog GC20Entrez Gene (Human): 10289SwissProt (Human): O60739Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : MGSSHHHHHH SSGLVPRGSH MSTIQNLQSF DPFADATKGD DLLPAGTEDY IHIRIQQRNG RKTLTTVQGI ADDYDKKKLV KAFKKKFACN GTVIEHPEYG EVIQLQGDQR KNICQFLLEV GIVKEEQLKV HGF 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.
