Fluorescein (FAM) is a xanthene dye, a parent of fluorescein dye series. This is a hydrazide derivative for the labeling of carbonyl compounds, aldehydes, and ketones.
Fluorescein is a bright dye that is compatible with a great number of instruments.
Carbohydrates are also often labeled with hydrazides by a protocol involving their oxidation with periodate first, and reacting with dye hydrazide after it.
荧光素 (FAM) 是一种呫吨染料，是荧光素染料系列的母体。 这是一种酰肼衍生物，用于标记羰基化合物、醛和酮。
荧光素是一种与许多仪器兼容的明亮染料。
碳水化合物也经常用酰肼标记，方法是先用高碘酸盐氧化，然后再与染料酰肼反应。
