Vibrio cholerae TaqMan PCR Detection Kits

Overview

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

Vibrio cholerae is a comma-shaped, gram-negative bacterium. It is the cause of cholera in humans, which affects the upper small intestine. Transmission of the disease is mainly through contaminated food or water. Human subjects affected by cholera exhibit severe watery diarrhea and vomiting, caused by the cholera toxin produced by the bacterium. Many cases of cholera are life-threatening, as diarrhea and associated vomiting can lead to rapid dehydration and electrolyte loss. Even with the extensive research on its epidemiology, cholera still affects over 5 million people per year worldwide.

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.
