What Are MiSeq and HiSeq?

Genetic sequencing powerhouse Illumina has developed a huge variety of sequencing platforms to choose from, all with different capacities and applications. Selecting the most appropriate sequencing platform depends on the type of study you are performing, and if short-read sequencing is your method of choice, two of the leading choices are the MiSeq and HiSeq platforms.

The HiSeq platform is a high-throughput platform that has the unique feature of switching between a rapid output mode and a higher output but slightly slower mode, depending on the size of the study. HiSeq runs produce paired-end reads of around 250 bp. However, this platform has recently been discontinued by Illumina, and will only be supported through 2023.

For current and future applications, MiSeq will go from HiSeq’s competitor to its successor. The MiSeq system comes with pre-optimized library preparation kits depending on the type of study and combines the rapid output capacity of HiSeq with slightly longer paired-end 300 base pair reads. This more streamlined approach, both faster and higher output, makes MiSeq an advantageous choice for high-throughput studies.

Applications of Short-Read Sequencing

So why use Illumina, and specifically MiSeq? For targeted sequencing analyses, for example, when the gene(s) of interest are well-established in reference genomes already, a short-read approach can be faster and more cost-effective than whole genome or long-read sequencing.
