The full-length genome was amplified directly from the RNA extracts from the clinical samples and the corresponding isolates, to obtain PCR products overlapping by 120 bp and covering the entire 29,903 bp viral genomic sequence. All the pooled barcoded libraries were purified using AMpure XP beads (Beckman Coulter) followed by adapter ligation with the NEBNext UltraII Ligation module. Next-generation sequencing generates masses of DNA sequencing data, and is both less expensive and less time-consuming than traditional Sanger sequencing. Recap of the development of next-generation sequencing (NGS) platforms from 2005 to 2015 followed by a brief outlook into the year 2020. Nevertheless, for all the specimens, the extremities of the genome could not be obtained. (2019). Our results highlighted the great potential of the amplicon-based approach to obtain consensus genomes of SARS-CoV-2 from clinical samples in just a few hours. This laboratory-based course is directed at scientists who will be generating and interpreting sequence information in their research and wish to gain a better understanding of the platforms and techniques involved, and their applications. Moreover, specific amplification-based approaches are proven successful since they can generate sufficient quantities of the genetic material needed for next-generation sequencing (Quick et al., 2017). Although higher samples multiplexing is suitable, these relatively low throughput sequencers can also run economically with a small number of samples, which is a great advantage when the information is needed as quickly as possible.
