Background
RT-qPCR technique is the current world-wide method used for the early detection of SARS-CoV2 RNA in the suspected clinical samples. Viral RNA extraction is the key pre-analytical step for SARS-CoV2 detection which often achieved using commercial RNA-extraction kits. However, due to the COVID-19 pandemic, bulk production and the supply chains for the commercial RNA-extraction kit have been seriously compromised. The shortage of commercial RNA-extraction kit is even more acute in developing country. Furthermore, use of one-off design RNA-columns can generate plastic wastes that have an environmental pollution effect.
Methods and results
To address these issues, in this study, we used warm alkaline solution containing Triton X-100 for the complete removal of the residual SARS-CoV2 RNA from the used RNA-binding silica column. Columns regenerated using the alkaline solution have the viral RNA purification capability that is comparable to the fresh silica columns. We also demonstrated that RNA-binding silica columns can be regenerated and reused for a minimum of five-times.
Conclusions
Therefore, the use of the RNA-column regeneration method may benefits several SARS-CoV2 diagnostic laboratories throughout the world by cutting down the requirement of commercial RNA-purification column.
