产品介绍
我们的Nuclear Violet DCS1是一种非荧光，DNA选择性和细胞不透性的紫色荧光染料，用于分析死细胞中的DNA含量。 核紫色DCS1在与双链DNA结合后具有明显增强的荧光。 它可用于荧光成像，微孔板和流式细胞仪应用。 这种DNA结合染料可用于死细胞的多色分析。

染色细胞分析方案
注意：以下方案适用于大多数细胞类型。 生长培养基，细胞密度，其他细胞类型和因子的存在可能影响染色。 玻璃器皿上的残留洗涤剂也可能影响许多生物的染色，并导致在有或没有细胞存在的溶液中出现明亮染色的物质。
工作溶液配制
使用缓冲液将核紫 DCS1储备溶液（5mM）稀释到0.5-5μm的浓度。
操作步骤
1.将Nuclear Violet DCS1工作溶液加到固定、死亡或凋亡的细胞（悬浮液或粘附细胞）中，并将细胞染色15至60分钟。 在最初的实验中，最好尝试几种染料浓度来确定产生所需结果的最佳浓度。 高染料浓度倾向于引起其他细胞结构的非特异性染色。
2.用荧光显微镜、荧光酶标仪或流式细胞仪直接检测染色细胞。
