【摘要】 荧光漂白恢复(fluorescence recovery after photobleaching, FRAP)技术作为定量分析细胞质膜流动性的关键手段之一,在细胞膜动力学研究领域具有广泛的应用价值。囊泡运输(包括胞吞作用与胞吐作用)作为细胞内外物质交换的核心生物学过程,其运行机制高度依赖于质膜的流动性。基于科教融合的教学理念,在“细胞生物学实验”研究生课程中融入FRAP技术实验模块,其核心目标在于引导学生探究“囊泡运输”与“细胞质膜流动性”的内在相关性。该实验教学体系不仅充分凸显了FRAP技术在活细胞动态监测中的独特优势,更通过“理论知识–实验操作–数据分析”的完整训练体系,强化了学生对膜流动性与囊泡运输等基础理论知识的理解;并通过引导学生探究膜异质性及微聚体空间组织特性等细胞生物学前沿科学问题,拓展了其学术视野,为后续开展膜蛋白相关研究奠定了方法学基础。更多还原

【Abstract】 FRAP(fluorescence recovery after photobleaching) is a crucial technique for quantifying plasma membrane fluidity and is widely used in the study of cell membrane dynamics. Vesicle trafficking, which includes processes such as endocytosis and exocytosis, represents a fundamental cellular activity essential for the exchange of substances between intracellular and extracellular compartments. Its function efficiency is closely tied to the fluidity of the plasma membrane. Guided by the principle of integrating research and education, this project introduces an FRAP module into the “Cell Biology Experiment” course for graduate students, aiming to elucidate the intrinsic relationship between “vesicle trafficking” and “membrane fluidity”. The experimental teaching framework emphasizes FRAP’s unique capability to monitor real-time live-cell dynamics, while establishing a comprehensive training system that integrates “theoretical knowledge-experimental operation-data analysis”. This approach deepens students’ understanding of core scientific concepts, such as membrane fluidity and vesicle trafficking, as well as membrane heterogeneity and nanocluster organization, laying a solid methodological foundation for future in-depth studies of membrane proteins.更多还原
