Synonym TFIIB Transcription Initiation Factor IIB; General Transcription Factor TFIIB; S300-II; GTF2B; TF2B; TFIIB
Background Transcription Initiation Factor IIB (TFIIB) is an essential factor for transcription by RNA Polymerase II. TFIIB localizes to the nucleus where it forms a complex (the DAB complex) with transcription factor IID and IIA. TFIIB plays a role as a bridge between IID, which initially recognizes the promoter sequence, and RNA polymerase II. TFIIB is involved in the selection of transcription start site.
Description Recombinant Human Transcription Initiation Factor IIB is expressed by our E.coli expression system and the target gene encoding Met1-Leu316 is expressed with a GST tag at the N-terminus.
Source E.coli
AA Sequence Met1-Leu316
Purity >85% as determined by reducing SDS-PAGE.
Endotoxin <0.1 ng/µg (1 EU/µg) as determined by LAL test.
Formulation Recombinant Human TFIIB Protein was lyophilized from a 0.2 μm filtered solution of 20mM TrisHCl, 100mM NaCl, pH 8.0.
Reconstitution Dissolve the lyophilized protein in distilled water.
Usage For Research Use Only
Storage Human TFIIB 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.
