The BD FACSLyric™ with the BD Fortessa™ X-20 is a type of flow cytometer used to analyze cells and their characteristics, such as size, complexity, and fluorescent labeling. The BD Fortessa™ X-20 has five lasers, which means the device can use five different wavelengths of light to measure the fluorescence of cells in real-time.

The five lasers allow the simultaneous excitation of multiple fluorochromes commonly used to label different cell components or markers. This provides researchers with the ability to gather detailed information about cellular characteristics, such as cell count, type, and how they respond to certain treatments.

In short: the BD Fortessa X-20 with five lasers enables versatile and detailed analyses by measuring multiple fluorochromes at once, resulting in deeper insights into cell properties.
