R821 Tricolor Multichannel Fiber Photometry System

R821 tricolor multichannel fiber photometry system is compatible with optoelectronics equipment. It has different wavelengths of excited light, 410nm, 470nm or 560nm, of which 410 is used to acquire reference signal and eliminate noise. The system can record signal of green fluorescence indicator like GCaMP and dLight or neurotransmitter probe and red fluorescence indicator like RCaMP, jrGECO1a or neurotransmitter probe.

And also it can be applied to record the neural signal for 9 sites at the same time.

The fiber photometry system records changes in the fluorescence intensity of neurons in a specific brain area to reflect neuronal population activity. In the study of neural circuits, the fiber photometry system can perform long-term stable monitoring of the neurons of freely moving animals, and explore the correlation between neural activity and animal behavior.

  • Main Applications:
    Ca2 + and neurotransmitter signal detection
    Study the function of neural circuits
    Explore the mechanisms of neurological diseases
    Develop new fluorescent sensor probe
    Experiment of optical principle
  • Advantages
    Three kinds of excitation light sources, that is 410nm、470nm and 560nm, are respectively used for excitation
    of reference, green fluorescence and red fluorescence;
