Source E.coli
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.
Purity Greater than 85% as determined by reducing SDS-PAGE.
Product Form Lyophilized
Formulation Lyophilized from a 0.2 μm filtered solution of 20mM TrisHCl, 100mM NaCl, pH 8.0.
Entotoxin Levels Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.
Reconstitution Dissolve the lyophilized protein in distilled water.
Storage 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.
Shipping The product is shipped at ambient temperature.
