用途: Fluorescein-PEG4-Acid is a xanthene dye with excitation/emission maximum 494/517 nm and a free terminal carboxyl acid. Terminal carboxylic acids can react with primary amine groups in the presence of of activators (e.g. EDC, or DCC) to form a stable amide bond. It can be used as a quantum yield standard. The hydrophilic PEG spacer increases solubility in aqueous media and reduces steric hindrance during binding. 物理化学性质: CAS号:1807518-76-8 常用中文名:Fluorescein-PEG4-acid 常用英文名:Fluorescein-PEG4-Acid 分子式:C32H34N2O11S 分子量:654.684 密度:1.5±0.1 g/cm3 沸点:892.9±75.0 °C at 760 mmHg 熔点:N/A 闪点:493.8±37.1 °C 储存条件:-20°C,避光,干燥,密封 |
