细胞内吞和细胞连接通透性是细胞生物学中的两个重要过程，对细胞的物质运输、信号传导和细胞间相互作用起着关键作用。FITC-Dextran因其分子大小和荧光特性，可以被用作探针来测量这两个过程。 细胞内吞： 原理：将FITC-Dextran与细胞共培养一段时间，细胞将 ...

原理：细胞间的连接结构（如紧密连接、间隙连接等）对物质的通透性具有调节作用。将FITC-Dextran施加到细胞外，通过观察其在细胞间的扩散情况来评估细胞连接的通透性。 应用：利用这一原理，可以研究不同细胞连接类型的通透性，以及在不同生理或病理条件 ...

在细胞生物学的研究领域，科学家们找到了一种创新的工具——葡聚糖偶联荧光素（Dextran4k-FITC），来深入探索细胞内吞和细胞连接通透性的奥秘。 Dextran4k-FITC，这一特殊的产品，以其独特的激发波长496nm和发射波长520nm，在荧光显微镜下呈现出明亮的绿色荧光。其分子量覆盖2k至2000k，为研究者提供了多种选择，以适应不同实验需求。 细胞内吞是细胞通过摄取外界物质来维持生命活 ...

Design Experiments were performed under basal and TGR5 agonist treatment. In vitro transepithelial electric resistance (TER) and FITC-dextran diffusion were measured in different cell lines. In vivo ...
