A Guide to Next Generation Sequencing Basics and Terminologies | Bioinformatics 101

In this video, I delve into the intricacies of a standard workflow for next-generation sequencing (NGS). We'll explore essential terminologies and concepts, including sequencing library preparation, multiplexing, sample pooling, as well as the roles of adaptors and barcodes. Furthermore, I provide an overview of different generations of sequencing technologies, spanning from the traditional Sanger sequencing to the advancements seen in Illumina, Ion Torrent, PacBio, and Oxford Nanopore sequencing technologies. I hope you find this video helpful! Leave your thoughts in the comment section below!

▸ Bridge Amplification:

▸ Sequencing by Synthesis (Illumina):

▸ What is sequencing depth/depth of coverage?

So informative!! And easily explained!! Perfect video for an in-depth overview of NGS. 👍

[gauravnjoshi]

Concise, precise and to the point. Thank you 🙏

[sebastianrodriguez]

Thanks for this! It was a very nice explanation. Kind regards from Ecuador.

Please, increase your frequency of uploading these great videos.

[KasraArbabiZaboli]

Many Thanks for your great comprehensive videos. they are really helpful. Could you please make another video for WES analysis pipeline on linux? or at least mention the major differences of WGS and WES analysis steps? looking forward your useful help. thanks

[Ankityadav-gqos]

Very informative video i have a one Question for you is there any difference between DNA fastq file and RNA fastq file? How can we define that without doing any analysis on that

[KasraArbabiZaboli]

thanks a lot for your comprehensive videos. could you please make another video for Whole Exome Sequencing analysis Pipeline or at least describe the differences between WGS and WES analysis piplines? many thanks

[sanjanaghosh]

Can you make a video elaborating about the data analysis? It would be of great help. Thank you.

[mahachaccour]

thank you for your videos. can you please make a video about how to use scGPT.

[Wuhan.Huazhong]

can you please talk about basics commands and pipeline for ATAC-seq, Cut and tag-seq

[amritabhattacharjee]

can you plz upload the papers/provide the link of the papers that you cited in the video?
