RNA-Seq: a revolutionary tool for transcriptomics. The MiSeq benchtop instrument utilizes a double-sided, single-lane flow cell and reagent cartridge supplied in kit form. Sequencing is performed by recording the synthesis of DNA strands in clusters of sample templates attached to the flow cell. Sequential interrogation of bases allows for the flexible adjustment of read length during a run.

Up to 96 samples may be sequenced in a single run with DNA libraries prepared with indexed or bar-coded adapters. The capacities of the single lane flow cell and the possible MiSeq applications are shown in the following tables. The purpose of this process is to amplify the signal intensity of the base to meet the signal requirements for sequencing. When cluster generation is complete, those templates are ready for sequencing.

The sequencing method is based on sequencing-by-synthesis SBS. DNA polymerase, connector primers and 4 dNTP with base-specific fluorescent markers were added to the reaction system. Then, buffer solution needed for fluorescence excitation are added, the fluorescence signal is excited by laser, and fluorescence signal is recorded by optical equipment. Finally, the optical signal is converted into sequencing base by computer analysis. Figure 4. The 4th step: alignment and data analysis.

The above is Illumina NGS chemistry overview, the SBS technology allows single-end and two-end sequencing, improves the ability to fully identify any genome. Your email address will not be published. Posted on October 17, by admin — No Comments.
