What is Illumina NovaSeq X / X Plus?

DNA sequencing is the process of working out the order of the chemical bases, the letters, that make up DNA. Knowing those sequences has become indispensable for medical diagnosis, biotechnology and basic biological research, but reading whole genomes means handling huge amounts of DNA. The NovaSeq X and NovaSeq X Plus are DNA sequencers from Illumina, part of its NovaSeq X Series. Illumina lists the series among the platforms using its XLEAP-SBS chemistry, a version of sequencing by synthesis, in which a fluorescently labeled building block is imaged as each base is added to a growing DNA strand and then removed so the next base can be added, detecting bases in a massively parallel way.
