Catalog No.: BL-0251NP
Product Overview
| Tag | GST |
| Host Species | Human |
| Accession | Q00403 |
| 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. |
