Recombinant Human Eukaryotic Translation Initiation Factor 1B/EIF1B is produced by our E. coli expression system. The target protein is expressed with sequence (Met1-Phe113) of Human EIF1B fused with a His tag at the N-terminus.
Reinheit
> 95 % as determined by reducing SDS-PAGE.
Sterilität
0.2 μm filtered
Endotoxin-Niveau
Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test
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.
Buffer
Lyophilized from a 0.2 μm filtered solution of 20 mM TrisHCl, 500 mM NaCl, pH 8.0.
Handhabung
Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
Lagerung
4 °C/-20 °C/-80 °C
Informationen zur Lagerung
Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
Eukaryotic Translation Initiation Factor 1B (EIF1B) is an element of a complex involved in recognition of the initiator codon during the scanning process. Translation is also initiated by the function of EIF1B in regulating the activity of ribosomal subunits 43S, 48S and 40S. EIF1B enables 43S ribosomal complexes to distinguish between cognate and near-cognate initiation codons, perceiving the nucleotide content of initiation codons.
