YGR®Inactivated Virus Sampling Kit

Product Application

This guanidine salt–based inactivation disposable virus sampling tube is specifically designed for the safe collection, inactivation, and transport of clinical specimens, including COVID-19, influenza, hand-foot-and-mouth disease (HFMD), norovirus, and rotavirus. It is fully compatible with most commercially available viral nucleic acid extraction kits.

Developed by YUGOMED, the proprietary guanidine-based virus inactivation reagent rapidly and effectively disrupts viral components while preserving the integrity of viral nucleic acids. This minimizes the risk of false-negative results during nucleic acid testing. Post-sampling, the tube does not require refrigerated transport (2–8°C). It can maintain nucleic acid stability at room temperature (RT) for up to 48 hours without affecting quantification results, and can still support reliable detection in positive samples after 7 days at RT, significantly reducing logistical and storage costs.

Product Advantages

• Rapid and Complete Viral Inactivation
  The YGR inactivated sampling system achieves 100% inactivation of viral samples, including COVID-19, within 5 minutes of contact.

• Stable Nucleic Acid Preservation
  Nucleic acid remains stable in YGR tubes, with no significant change in Ct values within 48 hours. Even after 7 days, variation in Ct values remains below 5%, ensuring high reliability in test results.

• Optimized Formulation with Balanced Guanidine Salt Levels
  Excessive guanidine concentrations can elevate Ct values, increasing the risk of false negatives. YUGOMED’s carefully calibrated reagent delivers effective inactivation while maintaining RNA integrity, ensuring accurate downstream detection.
