High-Yield T7 In Vitro Transcription Reagent: Exposing the Power of Single Nucleotide Modifications

RNA research is always evolving, and experts are now diving deeper into the intricacies of RNA structure and function. Hi-Yield T7 In Vitro Transcription Reagent stands as a key player in this exciting scene, providing researchers with a powerful tool to study the influence of single nucleotide modifications on RNA behavior.

What is Hi-Yield T7 in vitro transcription reagent?

In addition to traditional high-efficiency T7 RNA transcription kits, Hi-Yield T7 In Vitro Transcription Reagent focuses on a single component: a nucleoside triphosphate (NTP) modification called N1-Methyl-pseudouridine triphosphate (N1-Me-pUTP) . This unique NTP modification plays a crucial role in improving the stability and functionality of the RNA.

The power of N1-Me-pUTP:

Normal RNA transcripts can be degraded by enzymes called RNases. N1-Me-pUTP makes a slight modification to the position of uridine inside the RNA molecule. Thanks to this modification, a methyl group is introduced, which acts as a protection against RNase attack, which improves the stability and lifespan of the RNA produced.

The benefits of Hi-Yield T7 in vitro transcription reagent:

RNA Stability significantly improves with the incorporation of N1-Me-pUTP, allowing extended storage and handling time without risk of degradation.

Functional Studies: 

The subtle modifications made by N1-Me-pUTP are often similar to natural modifications present in functional RNAs. This allows researchers to analyze the influence of these modifications on interactions between RNA and protein, enzymatic activity and cellular activities.

Adaptation and Compatibility:

The High-Yield T7 In Vitro Transcription Reagent can be seamlessly integrated into existing T7 RNA transcription kits. Just replaces part of the UTP standard with N1-Me-pUTP in order to achieve the desired level of modification.

Applications of Hi-Yield T7 in vitro transcription reagent:

By integrating N1-Me-pUTP into small interfering RNA (siRNA) molecules, researchers can improve their stability and effectiveness within the cell, leading to greater efficiency in gene silencing.

Aptamer Formation: 

Aptamers are RNA or DNA oligonucleotides that bind to specific targets. N1-Me-pUTP modification can improve the stability and affinity of aptamers, making them valuable tools for diagnostics and targeted therapies.

Enzyme Engineering: 

Ribozymes are RNA molecules that possess enzymatic activity. Incorporation of N1-Me-pUTP can improve the stability and catalytic activity of artificial ribozymes, which opens new prospects in the field of biotechnology.


Hi-Yield T7 In Vitro Transcription Reagent provides a valuable tool for RNA researchers. By enabling the incorporation of N1-Me-pUTP, researchers can access a new level of control over RNA stability and function, opening up avenues for groundbreaking discoveries in the field of RNA biology and its potential therapeutic applications.
