Category:ECO:0000222 ! Illumina sequencing evidence

name: Illumina sequencing evidence
def: "A type of high throughput nucleotide sequencing evidence in which sequence is determined through hybridization of adaptor-ligated DNA to a glass slide on which each fragment is simultaneously clonally amplified, followed by progressive rounds of base incorporation with fluorescently-tagged nucleotides, washing, imaging, and cleavage."

comment: In Illumina sequencing technology, adapters are ligated onto the ends of randomly fragmented DNA. After single-stranded fragments are bound to the inside surface of a flow cell channel, they undergo in-place bridge PCR amplification. To begin the sequencing cycle, labeled reversible terminators, primers and DNA polymerase are added, followed by laser excitation of the fluorescent label and high resolution scanning. After non-incorporated nucleotides are washed away and the dye is chemically removed, the next cycle repeats with four labeled reversible terminators, primers and DNA polymerase, again followed by imaging.
