Ex/Em: 494/523 nm Biotin-4-fluorescein是一种荧光标记的生物素衍生物，生物素与亲和素之间高亲合力的牢固结合以及多级放大效应，使得该产品能够准确定量生物样品中亲和素与链霉亲和素。 注意事项： Biotin-4-fluorescein是一种荧光标记的生物素衍生物，生物素与亲和素之间高亲合力的牢固结合以及多级放大效应，使得该产品能够准确定量生物样品中亲和素与链霉亲和素。 应用范围： 标记亲和素及链霉亲和素 Biotin-4-fluorescein is a fluorescently labeled biotin derivative. The strong binding of high avidity between biotin and avidin and the multilevel amplification effect enable the product to accurately quantify avidin and streptavidin in biological samples. Matters needing attention： Biotin-4-fluorescein is a fluorescently labeled biotin derivative. The strong binding of high avidity between biotin and avidin and the multilevel amplification effect enable the product to accurately quantify avidin and streptavidin in biological samples. Scope of application： Labeled avidin and streptavidin
