FluoCells™ 制备玻片#2（BPAE 细胞与小鼠抗-α-微管蛋白、BODIPY™ FL 山羊抗小鼠 IgG、Texas Red™-X 鬼笔环肽和 DAPI）

DAPI是一种非常普通的蓝色核复染荧光染料，能对固定和通透的细胞和组织的细胞核进行非常明亮的标记。遗憾的是，人们普遍认为它是介于半通透性到非通透性之间的染色剂，对活细胞的染色效果也不一致。Hoechst 33342染料是细胞通透性染料，与DAPI染色有相似的染色结合机制和荧光颜色；它是活细胞成像的首选，且对固定细胞的标记效果和DAPI一样好。

Some of the most popular are the FluoCells demonstration slides, which have cells or tissue sections that are labeled with three different dyes. FluoCells 1 and 2 have cultured cells, while FluoCells 3 is a tissue section (mouse kidney). Slides with fluorescent beads are also available.

DAPI is a very common blue-fluorescent dye for nuclear counterstaining and gives very bright labeling on nuclei in fixed and permeabilized cells and tissues. However, it is considered to be a semi-permeant to impermeant stain and provides inconsistent staining of live cells. Hoechst 33342 dye is cell-permeant and stains with the same binding mechanism and fluorescent color; it is preferred for live-cell imaging and is just as good as DAPI for fixed cell labeling.
