Swab:Direct™ Extraction Kit is designed to perform PCR test from nasopharyngeal and oropharyngeal swab samples without prior DNA/RNA purification process. The buffer includes high concentrated alkaline compounds for lysis and elution of sample organisms. This product is easy to use by just mixing the swab sample and extraction buffer without additional processes for preparing nucleic acid template to run PCR tests.

• To comparative experiments between Swab:Direct™ Extraction Kit and others, carried out using GAPDH gene extracted from sample collected by nasopharyngeal and oropharyngeal swab. Each sample was extracted five times per each method. Perform real-time PCR analysis of the extracted nucleic acid from each extraction method using GENECHECKER^® UF-300 Real-time PCR System. The relatively lower Ct value was identified than the other methods, which resulted in higher efficiency.
