for Recombinant TFIIE beta proteinContents

10 µg recombinant TFIIE β protein supplied in 20 mM Tris-HCl (pH7.3), 300 mM KCl, 0.2 mM EDTA and 20% glycerol. Please refer to product insert upon arrival for lot-specific concentration.

for Recombinant TFIIE beta proteinBackground

TFIIE beta, transcription factor II E beta (also known as TFIIEB, T2E2, general transcription factor IIE polypeptide 2, or GTF2E2) is required for promoter clearance by RNA polymerase, along with TFIIH.

for Recombinant TFIIE beta proteinApplication Notes

Recombinant TFIIE β protein is suitable for use in in vitro transcription assays. We recommend to start with a range of protein concentrations (e.g. 5 ng, 50 ng, and 500 ng) to determine the optimal amount needed for each in vitro transcription assay.

for Recombinant TFIIE beta proteinProtein Details

Recombinant TFIIE β protein was expressed in E. coli as the full-length human protein (accession number NP_002086) with an N-terminal FLAG-Tag. The molecular weight of the protein is 35 kDa.

for Recombinant TFIIE beta proteinStorage

Lyophilized proteins can be stored at -20°C or -80°C, preferably desiccated. Recombinant proteins in solution are temperature sensitive and must be stored at -80°C to prevent degradation. Avoid repeated freeze/thaw cycles and keep on ice when not in storage.

for Recombinant TFIIE beta proteinGuarantee
