Figure 2. T&A cloning of the amplified SARS-CoV2 spike gene PCR product from Korean COVID-19 YN patients. The PCR product of SARS-CoV2 spike gene from (A) YN1, (B) YN2, (C) YN3, and (D) YN4 was ligated into T&A cloning plasmid vector. The same forward (CoV2sF-2) and reverse (CoV2sR-2) primer amplified 719 bp of SARS-CoV2 spike gene PCR product from four YN patients. Representative data from 1 of 2 independent experiments performed are shown.
