DNA Sequencing Lasers

DNA sequencing is an extremely powerful tool which allows the identification of the four basic DNA molecules adenine (A), cytosine (C), guanine (G), and thymine (T) by tagging them with fluorescence reporter molecules.  This allows for the rapid determination of the precise order of A, C, G, and T molecules allowing for the entire DNA strand to be coded.  In DNA sequencing lasers are focused either through a flow channel (like in flow cytometry) or onto a microplate where the tagged molecules ordered and scanned.  Like all fluorescence applications, most of the visible wavelengths can be used in DNA sequencing, but it’s essential that all DNA sequencing lasers have a high quality TEM00 beam profile.  On this page, you will find a list of all of the full range of DNA sequencing lasers we offer at RPMC, including our multi-laser combiner.
