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 ...

This valuable study examines how different exercise training intensities affect intestinal barrier function and gut microbiota composition over a 6-week period in mice. The evidence supporting the ...

Get detailed information on Dextran, including pronunciation, uses, dosage guidelines, indications, and instructions on how and when to take it and when to avoid it. The updated prescription ...

‌酸性染料比色法‌是一种化学实验方法，在适当的pH值 介质，一些酸性染料(常用者多为磺酸酞类指示剂，如溴麝香草酚蓝、溴甲酚绿等)解离为阴离子(In’ )，而有机碱类与氢离子生成盐(BH' )，二者结合成配位化合物，即离子对。 此离子对被有机溶剂定量提取 ...

双硫键的引入使得该复合材料能够在特定的环境下（如肿瘤细胞或还原性环境中）触发药物释放或其他分子的释放。 在PLA-SS-PEG-FITC中，双硫键的存在可以使载体在还原环境中断裂，进而控制药物或分子的释放，增强靶向性和治疗效果。

FITC underscored the organisation’s significant achievements in 2023 and unveiled ambitious plans as it continues to drive innovation across the financial services and allied sectors. This was ...

We found that: (i) transport of fluorescent dextrans in brain parenchyma depended on dextran size in a manner consistent with diffusive rather than convective transport; (ii) transport of dextrans in ...
