Laser Microdissection ArcturusXT

Laser Microdissection ArcturusXT

Laser microdissection is a well-established method for isolating individual or subcellular structures from heterogeneous cell populations. The Arcturus System combines laser-capture and laser cutting in one device by offering two lasers (UV, IR). This offers flexibility in preparation, allowing you to use any slide type. The use of the IR laser is ideal for capturing single cells and/or small numbers of cells.
