Multiphoton microscopy (MPM) is well-suited for functional imaging deeper into biological tissues than what is possible with confocal microscopy. This imaging technique is commonly used in intravital imaging of healthy and diseased tissues and cells, with or without fluorescent labeling. Recent advances in multiphoton microscopy technology support fast, in vivo imaging with single-cell resolution and a large field of view. Integration of optogenetics with multiphoton imaging has opened new avenues in studying the computational performance of the brain in live animals.
At the forefront of scientific discoveries for nearly two decades, Bruker’s Ultima multiphoton imaging technology is a direct result of close collaboration and laboratory experience with leading neuroscientists around the world. These efforts have led to a host of unique capabilities and features found only on Ultima systems, such as our modular setup, incorporated photostimulation light path, and feature-rich Prairie View software.
Hear from researchers and experts on best practices, new techniques and discoveries, and ideas for new applications using two-photon microscopy.
