Fluorescence Lifetime Photometry System Product Introduction The Fluorescence Lifetime Fiber Photometry System connects to animals via optical fiber, enabling the detection of changes in the lifetime of fluorescent proteins in the brains of freely moving animals. Fluorescence lifetime refers to the duration that a fluorescent protein molecule remains in the excited state after being activated by light. It is not affected by non-experimental factors such as protein expression levels, and can change when binding to target substances, thus featuring excellent data consistency and anti-interference ability. This product uses a picosecond pulsed laser to excite fluorescent proteins of specific wavelengths and collects fluorescence lifetime signals through optical fiber, thereby realizing the detection of neural activity in freely moving animals and the quantitative study of the concentration of target substances such as neurotransmitters. Application Scenarios Circuit Analysis: Dynamically monitor fluorescence lifetime signals to analyze neural circuits in animals with free behaviors (e.g., the neural mechanisms of learning and memory encoding and social behavior). Pathological Research: Achieve long-term stable signal monitoring for chronic disease models (e.g., anxiety disorder, Alzheimer's disease). Quantitative Analysis: Realize the quantitative study of substances such as neurotransmitters (e.g., dopamine, acetylcholine) based on the lifetime changes of fluorescent probes. Molecular Biochemical Research: Study the conformational changes of protein molecules by utilizing the characteristic properties of flu
