A novel two-step, direct-to-PCR method for virus detection off swabs using human coronavirus 229E 2020-08-25 .txt text/plain 2980 169 52 Herein, we have developed a method to detect virus off swabs using solely shaker-mill based mechanical lysis and the transfer of the viral lysate directly to a PCR assay for virus detection, bypassing the substantial reagent and time investments required for extraction and purification steps. Swabs were spiked in serial dilutions from 1.2 × 10(6) to 1.2 × 10(1) copies/mL and then placed in 2 mL tubes with viral transport media (VTM) to mimic the specimen collection procedures in the clinic prior to processing via shaker-mill homogenization. RESULTS: HCoV-229E in vitro spiked swabs were processed in a novel two-step, direct-to-PCR methodology for viral detection. CONCLUSION: We have proven that the shaker-mill homogenization-based two-step, direct-to-PCR procedures provides sufficient viral lysis off swabs, where the resulting lysate can be used directly in PCR for the detection of HCoV-229E. Using human coronavirus 229E (HCoV-229E) as our model organism, we developed a novel two-step methodology of optimized shaker-mill homogenization parameters that allowed for direct-to-PCR viral detection. ./cache/cord-337636-3yc0ribg.txt ./txt/cord-337636-3yc0ribg.txt
