Invitrogen™ T7 RNA Polymerase

Synthesizes large quantities of RNA from DNA inserted into a transcription vector downstream from a T7 promoter. A T7 RNA Polymerase technical bulletin is available.

• Application: Synthesis of labeled and unlabeled RNA transcripts.
• Source: Purified from E. coli expressing the T7 RNA Polymerase gene on a plasmid
• Performance and Quality Testing: 3' and 5' exodeoxyribonuclease, ribonuclease, and DNA nicking assays; performance in a transcription reaction
• Unit Definition: One unit hydrolyzes 1nMol of ribonucleotide into acid-precipitable material in 1 hr at 37°C using a T7 transcription vector as template
• Unit Reaction Conditions: 40mM Tris-HCl (pH 8.0), 25mM NaCl, 8mM MgCl₂, 2mM spermidine-(HCl)₃, 5mM DTT, 0.4mM ATP, 0.4mM CTP, 0.4mM GTP, 0.4mM UTP, 1μCi [^{3H]GTP, 1μg SphI-cut pT7L13, and enzyme in 50μL for 10 min. at 37°C}
