用途: Fluorescein-PEG5-Acid is a xanthene dye with excitation/emission maximum 494/517 nm and a free terminal carboxyl acid. Terminal carboxylic acid 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:2183440-40-4 常用中文名:Fluorescein-PEG5-acid 常用英文名:Fluorescein-PEG5-Acid 分子式:C34H38N2O12S 分子量:698.74 密度:N/A 沸点:N/A 熔点:N/A 闪点:N/A |
