Inactivating Transport Media:
Safely Inactivate Pathogens and Preserve Nucleic Acids
Instantly inactivate pathogen (e.g. COVID-19 virus）in freshly collected clinical samples, reducing the infection risk of health care professionals during sample collection, transportation and testing.
Clinical samples remain stable in the tube for 15 days at room temperature; store samples at -20°C for long term storage.
Inhibit nucleases, thereby ensuring that the released nucleic acids are not degraded. Additional nucleic acid protecting ingredients in the preservation solution can protect nucleic acid, especially single-stranded RNA, so that RNA maintains stable in an alkaline environment. The product can protect clinical samples of COVID-19 that cannot be tested immediately or require long-distance transportation.
After clinical samples were collected and stored at -20 ℃, 4 ℃, room temperature, 37 ℃, 55 ℃ for 15 days, QPCR results showed that compared with the Ct value of the sample stored at -20 ℃, the changes of Ct values at other temperatures (△Ct) were 0.67 (4 ℃), -0.28 (room temperature), -0.88 (37 ℃), 0.45 (55 ℃); the absolute values of △Ct are all less than 1, proving that the samples were stable for 15 days.
