产品介绍
TWO-PRO -1在化学上等同于TO-PRO®-1（TO-PRO®是Invitrogen的商标）。TWO-PRO -1是一种碳花青二聚体，具有类似于FITC的绿色荧光。它不具有细胞渗透性，可以很容易地与Cy5和罗丹明区别开来，作为核复染和死细胞指示剂。在不存在核酸的情况下它是非荧光的，并且在与DNA结合后会产生非常明亮的荧光信号。TWO-PRO -1可在培养细胞和石蜡切片中进行强而有选择性的核染色。同时使用细胞可渗透的Nuclear Red LCS1染料和不渗透细胞的TWO-PRO -1进行标记，可用于评估细胞活力。TWO-PRO -1和Nuclear Red 的消光系数都比结合DNA的碘化丙啶大。
