Optogenetics has advanced neuroscience by offering millisecond-precision control over specific neuronal populations. This technique combines optical and genetic methods to express light-sensitive proteins (opsins) in targeted cells, allowing their activity to be instantly turned on or off with specific wavelengths of light.
As a preclinical contract research organization specializing in psychiatric disorders, our optogenetics platform is uniquely positioned to help you validate drug targets and evaluate candidate efficacy. By integrating this powerful technology with our extensive disease-relevant cell and animal models, we provide end-to-end solutions that bridge mechanistic research and drug development.

Optogenetics technology features two unique characteristics: high temporal and spatial resolution, and cell-type specificity. Its applications span multiple classic experimental animal species (including fruit flies, nematodes, mice, rats, marmosets, and cynomolgus monkeys, among others) and cover various aspects of neuroscience research. These include fundamental studies of neural circuits, learning and memory research, addiction studies, movement disorders, sleep disorders, Parkinson's disease models, as well as animal models of depression and anxiety.
This technology platform enables experiments and data analysis and processing in optogenetics, fiber photometry (including three-color single-channel and three-color multi-channel), calcium imaging, fine behavioral recording, electrophysiological monitoring and detection, pulse stimulation, and more.

In psychiatric research, accurately modeling pathological states and precisely evaluating the effects of drug interventions are of paramount importance. The advantages of our platform lie in:
As a specialist in psychiatry, we offer a seamless transition from cell-based assays to complex animal models of depression, anxiety, and schizophrenia .
We utilize optimized AAV vectors (AAV2/9, AAV5, etc.) with titers exceeding 1E+12 VG/mL to ensure robust and stable expression of opsins in target brain regions.
Our experts utilize high-precision stereotaxic injection and fiber-optic implantation protocols to ensure minimal damage and maximum targeting accuracy .
Beyond behavior, we provide electrophysiological recordings and calcium imaging to verify the functional impact of optogenetic manipulation in real-time .
What is the difference between ChR2 and eNpHR3.0?
ChR2 (Channelrhodopsin-2) is used for neuronal excitation via blue light (470nm), while eNpHR3.0 (Halorhodopsin) is used for neuronal inhibition via yellow light (590nm)
How long after virus injection can behavior tests begin?
Typically, optimal opsin expression is achieved within 2-4 weeks post-injection, depending on the promoter and viral serotype used.
Can you perform optogenetics in free-moving animals?
Yes, our platform is equipped for wireless or tethered fiber-optic stimulation in freely behaving mice and rats.
