| 产品详情(用途,包装等)
用途: The single isomer, 6-FAM, contains a carboxylic acid that can be used to react with primary amines via carbodiimide activation of the carboxylic acid. Fluorescein is the most common fluorescent derivatization reagent for labeling biomolecules. In addition to its relatively high absorptivity, excellent fluorescence quantum yield, and good water solubility, fluorescein has an excitation maximum that closely matches the 488 nm spectral line of the argon-ion laser. 物理化学性质: CAS号:3301-79-9 常用中文名:6-羧基荧光素 常用英文名:6-Carboxyfluorescein 分子式:C21H12O7 分子量:376.316 密度:1.7±0.1 g/cm3 沸点:736.4±60.0 °C at 760 mmHg 熔点:>300 °C(lit.) 闪点:271.0±26.4 °C 储存条件:2-8°C |
