OverView

T7 RNA Polymerase catalyzes the formation of RNA from a DNA template in the 5’-3’ direction and is commonly used in in vitro transcription (IVT) applications. The enzyme is T7 promoter specific, requires Mg²⁺ as a cofactor and can use modified nucleotides for the synthesis. The T7 RNA Polymerase requires a double-stranded DNA template and can produce full-length RNA transcripts.

Key Features

• T7 promoter-specific RNA polymerase
• Available in standard glycerol-based formulation as well as lyophilization-friendly formulation without glycerol.

‍

Suggested Applications

• In vitro transcription of RNA
• Molecular diagnostics (NASBA and other)

Overview

• Detection kits for Clostridium difficile
• CE-IVD marked version available for in vitro diagnostic use
• Available in TaqMan format for analysis

Clostridium difficile is rod-shaped, gram positive bacterium. It is the main causal agent of antibiotic-associated diarrhea and pseudomembranous colitis. The colonization of intestines by C. difficile is usually associated with the elimination of natural intestinal flora as a result of antibiotic application and is frequently reported in health care centers. While C. difficile infection could be severe and life-threatening, particularly among the elderly, many patients are asymptomatic making diagnosis challenging during outbreaks. The tradition method of detecting C. difficile infection is by cytotoxicity test of the toxin produced by the bacterium, but such protocols usually require extensive time before conclusion can be made.

Storage Conditions and Product Stability
All kit components can be stored for 2 years after the date of production without showing any reduction in performance.

All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 2 x) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.
