Basic Fiber Photometry System
-
In conventional fiber photometry systems for behaving animals, the fiber-optic rotary joint transfers light signals and allow fiber tether rotation. However, by doing so, the optical joint introduces some transmission losses and rotation-related optical signal variation, which might not be acceptable for all applications. Those drawbacks are eliminated if the so-called Rotary Fluorescence Mini Cube (RFMC) with integrated LEDs and detectors is mounted on a rotating side of a 24-channel Assisted Electrical Rotary Joint. This approach enables both one- and two-site photometry recordings depending on the number of attached cubes.
Currently, we offer LED light sources for GCaMP, GCaMP with Red Fluo, and FRET(CFP/YFP). Customization with other light sources, such as laser diodes and different fluorophore combinations, might be possible if requested.
- The GCaMP Fiber Photometry System measures the 405 nm excited GCaMP fluorescence (isosbestic point), and the 470 nm excited calcium-dependent GCaMP fluorescence, on a single photodetector. The fluorescence emission can be demodulated by lock-in amplifier detection, or by interleaved excitations.
The GCaMP Fiber Photometry System includes :
- Fiber Photometry Console, the core of the system
- 2-channels LED Driver to control LED power
- Fluorescence Mini Cube - GCaMP with built-in LEDs and DETECTOR
- Doric Neuroscience Studio software
Add optional items :
- Pigtailed 1x1 Fiber-optic Rotary Joint with Holder (fixed and gimbal)
- Pigtailed 2x2 Fiber-optic Rotary Joint with Holder
- Fiber Photometry Cannula Holder to record during surgery
- Fiber Photometry Rack with parts pre-assembled
- Optical Power meter to monitor and calibrate excitation power
Complete your system with :
-
Low autofluorescence optical patch cords to bring light to the animal
- Fiber-optic Cannulas for chronic implant
- Mating sleeves for the ferrule to ferrule interconnect
NOTE : Other light sources, such as laser diodes, and different fluorophore combinations are possible. Please do not hesitate to request your preferences. - The GCaMP with Red Opsin Fiber Photometry System measures the 405 nm excited GCaMP fluorescence (isosbestic point), and the 465 nm excited calcium-dependent GCaMP fluorescence, on a single photodetector. The fluorescence emission can be demodulated by lock-in amplifier detection, or by interleaved excitations. It also has an optical fiber input port (FC) to connect the light source for red opsin activation or inhibition.
