Key Features

  • Consolidated design—precise IR laser capture microdissection and UV laser cutting in one single instrument
  • Fast functioning—rapid isolation of specific cells in four simple steps
  • Open, modular platform—flexible to suit numerous research needs
  • Easy, intuitive operation—simplified workflow through streamlined interface
  • Flexible sample prep—wide range of slide types and sample preparations supported

A Unique Offering of Laser Capture and Laser Cutting Microdissection

The solid-state IR laser—exclusive to the ArcturusXT™ microdissection system—delivers a gentle capture technique, which preserves biomolecular integrity and is ideal for single cells or a small number of cells. The solid-state UV laser offers unprecedented speed and precision, well-suited for microdissecting dense tissue structures and for rapidly capturing large numbers of cells.

Rapidly Isolate Pure Cell Populations for Microgenomic Analysis

Laser capture microdissection allows for rapid isolation of specific cells in four simple steps. After locating the cells of interest, the CapSure® LCM Cap is placed over the target area. Pulsing the ArcturusXT™ System laser through the cap activates the film on the cap to adhere to the target cells. Lifting the cap removes the target cells now attached to the cap. The isolated cells  are now available for extraction of biomolecules.

Modular Flexibility to Fit Your Needs

The ArcturusXT™ microdissection instrument is modularized to suit any dynamic research need (Figure 1). The system utilizes a Nikon Eclipse Ti-E inverted research microscope with a variety of options available at the time of purchase or post-purchase. Each instrument has IR-enabled LCM, an interactive pen-display monitor, and a trackball actuated stage for easy and ergonomic navigation. Additional modules that may be added include LED brightfield illumination or high-intensity halogen illumination, enabling phase contrast and differential Interference contrast (DIC) microscopy applications.

The ArcturusXT™ system may be purchased with or without UV laser cutting and attenuable fluorescence. A wide range of objectives are available, including a 2x –100x dry objective and a 100x oil-immersion objective. For ultimate image quality and analysis, a high-resolution megapixel camera may be added.

Ultimate Flexibility in Sample Source and Preparation

The unique combination of IR laser capture and UV laser cutting permits the use of many slide types including glass, glass membrane, and framed membrane slides for contact or non-contact microdissection. In addition, a variety of specimen preparations may be used (Figures 3, 4, and 5).
