Operetta CLS

The Operetta CLS high-content analysis system has all the speed, sensitivity and resolution you need to characterize fine sub-cellular details . The Operetta is designed for fully-automated high-capacity, quantitative cellular analysis of fixed or live cells. It contains the highly sensitive sCMOS camera that provides a large field of view and high resolution image capture. The Operetta's Harmony software lets you find even subtle phenotypic changes.

Tips & tools for data collection and interpretation:

PerkinElmer’s Harmony software is used to acquire images on the Operetta CLS high-content fluorescent microscope and can also be used to create custom automated image analysis methods.

Harmony, like most automated image analysis software, requires the use of fluorescent dyes, antibodies, or expressed proteins to tag the nucleus and/or the cytoplasm to differentiate separate regions of interest from background. To use "image segmentation" to identify cells and cell compartments, fluorescent channels are a critical starting point for all analysis methods to ensure successful image acquisition, and to allow for the creation of robust data analysis methods. Brightfield cannot be used to perform image segmentation within the Harmony software.
