Next-Gen sequencing


Our sequencing experience on MiSeq at 2x300 b

Illumina sequencing technology is commonly referred to as short-read technology. In practice this means that it typically produces reads of hundreds of bases in length. Its current technological maximum in terms of read length is a kit for the MiSeq system that allows reading up to 600 b (2x300 setting). In this article, we have taken a closer look at some of the problems associated with this type of sequencing.

Quantity and quality of GridION data

In the last article we have described some features and consequent limitations of Sequel sequencer (Pacific Biosciences). If you are looking for an alternative to this long read technology, you might be considering the technology of Oxford Nanopore.

Quantity and quality of Sequel data

Pacific Biosciences SMRT sequencing technology enables sequencing of fragments of both tens of kilobase and hundreds of bases in length.

Sequencing low-diversity libraries on Illumina

Illumina sequencing technology is currently dominating the market. It offers a number of advantages over other technologies but unfortunately this does not mean that it is completely free of imperfections.

Several good reasons why Qubit is better than Nanodrop when quantifying your samples for NGS library prep

If I had a nickel for every time we answered the “How should I quantify my DNA or RNA for NGS library prep?” question, I wouldn’t need to be writing this article. I’d be on a boat in the Mediterranean. But since I’m not on a boat anywhere, I thought I could perhaps collect several good reasons why using Nanodrop is not really the best way of doing this.

A few thoughts on data analysis

The technology of next-generation sequencing produces huge amounts of data compared to Sanger technology. Its volume naturally depends on the design of the experiment, but primarily on the output capacity of the instrument. In principle, it is always necessary to deal with the transfer of large amounts of data into a form which enables their effective processing to allow a deeper analysis of the sequences obtained which is the very aim of the experiment.
