The increasing use of the baculovirus expression vector system (BEVS) has generated significant interest into techniques for quantifying baculovirus stocks. One method involves the use of quantitative real-time polymerase chain reaction (PCR). This study investigated simplifying baculovirus sample preparation for quantitative Real Time PCR to provide an alternative to current kit-based preparation methods. To achieve this goal, combinations of freeze/thaw cycles and Triton X-100 treatment were investigated. A treatment with only Triton X-100 was found to be sufficient to provide a simple, rapid and cheap alternative to kit-based preparation methods. This study also examined other factors such as primer choice to further examine the process of baculovirus quantitation by qPCR.
► Comparison of qPCR quantitation of baculovirus using sequences from the Ie-1 and Gp-64 genes. ► Baculovirus DNA preparation using Triton X-100. ► Comparison of baculovirus titers using qPCR and flow cytometry.
