The Xenogen IVIS 200 System allows researchers to use real-time imaging to monitor and record cellular and genetic activity within a living organism. Features of the system include a custom lens with 5-position carousel and adjustable field of view of 4-25 cm, more uniform light collection, and improved resolution with single cell sensitivity for in vitro use.
