Description | 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. |

Amino Acid | Met1-Leu316 |
Construction | Met1-Leu316 |
Protein Purity | Greater than 81% as determined by reducing SDS-PAGE. (QC verified) |
Molecular Weight | 62 KDa (reducing condition) |
Endotoxin | < 0.1 ng/µg (1 EU/µg) as determined by LAL test. |
Formulation | Lyophilized from a solution filtered through a 0.22 μm filter, containing 20 mM Tris-HCl, 100 mM NaCl, pH 8.0. |
Reconstitution | Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing. |
Stability & Storage | Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots. |
Shipping | In general, Lyophilized powders are shipping with blue ice. Solutions are shipping with dry ice. |
