Sequence Positions
Met1-Leu316
Species
Human
Endotoxin
< 1.0 EU per ug as determined by the LAL method.

Reconstitution
We recommend that the vial be centrifuged to opening to bring the contents to the bottom. Do not mix by vortex. It is recommended that sterile water(50ul) be added to the vial to prepare a stock solution of 0.2mg/mL. Concentration is measured by UV-Vis.
Preparation and Storage
Ships on blue ice. Lyophilized proteins are stable for up to 12 months when stored at -20 to -80 degree C. Reconstituted protein solution can be stored at 4-8 degree C for 2-7 days. Aliquots of reconstituted samples are stable at < -20 degree C for 3 months.

Related Product Information for TFIIB/GTF2B recombinant protein
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.

Product Notes
The TFIIB/GTF2B gtf2b (Catalog #AAA174034) is a Recombinant Protein produced from E.coli and is intended for research purposes only. The product is available for immediate purchase. The immunogen sequence is Met1-Leu316. It is sometimes possible for the material contained within the vial of "Transcription Initiation Factor IIB/TFIIB/GTF2B, Recombinant Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
