Flexible Architecture to Meet Varying Requirements

Ultima In Vitro is the ultimate “slice rig," having provided the platform on which leading scientists have conducted breakthrough experiments in brain slices related to neural signaling and neural networks for more than ten years. The system provides the flexibility for the most demanding protocols, and is available on upright or inverted optical microscopes. Features include: 

  • Secondary scan path that enables simultaneous imaging and photostimulation
  • Visible, UV, and IR inputs for photostimulation
  • Sub-micron positioning control for point photoactivation
  • Sub-millisecond spirals for somal actiavtion
  • Synchronization and triggering to enable simultaneous imaging, photostimulation, and electrophysiology
  • Integrated electrophysiology control and recording with up to 16 analog outputs/inputs

High-Resolution Multifield Imaging

5x5 montage at 40x (covering area of 1175 um x 1175 um) of mouse kidney section with Alexa Fluor® 488 WGA, Alexa Fluor® 568 Phalloidin.

The Atlas Imaging module in Prairie View software simplifies setup of 2D and 3D automated montages. X,Y boundaries are easily setup through a thumbnail display. Tiles not containing areas of interest can be turned off, and the Z range for 3D montages can be variable, allowing more efficient collection of data.
 

Pharmaceutical Studies with Tissue Explants

Tissue explants provide a higher throughput model for studying tissue response to pharmaceutical agents. The FLIM option allows measurement of metabolic status through measurement of fluorescent lifetimes.
