T7 RNA polymerase is widely used in molecular biology for in vitro transcription applications. It efficiently synthesizes RNA from DNA templates that contain the T7 promoter sequence. This enzyme is essential for producing high yields of RNA for use in RNA interference studies, riboprobe generation, and structural biology. It is commonly employed to generate mRNA for transfection, antisense RNA, and functional RNA molecules like aptamers and ribozymes. The inclusion of 10X transcription buffer ensures optimal reaction conditions, enhancing enzyme stability and transcription efficiency. Due to its high specificity and activity, T7 RNA polymerase is a key tool in recombinant protein expression systems and synthetic biology workflows.
