DAPI(4',6-二脒基-2-苯基吲哚二盐酸盐)是一种蓝色荧光染料,能结合双链DNA富含AT的区域,结合时荧光增强约20倍,荧光增强的程度与存在的DNA数量成正比,荧光最大发射波长在约454nm处。该复合物在室温和pH值4 - 11范围内可稳定数小时。DAPI也可以通过AU选择性插入与RNA结合,不过DAPI/RNA复合物发射波长较长(500 nm),且荧光量子产量仅增加约20%。DAPI在多色荧光应用中被广泛用作检测细胞核的反染色剂,其蓝色荧光与用于染色其他结构的红色、黄色或绿色荧光染料形成鲜明对比。它也被用于研究细胞凋亡(在低浓度下,染料不能进入活细胞,但可以穿透死亡或受损细胞),以及定量DNA分析、原位杂交、染色体分选和支原体检测分析。

Data Figures

Staining Profiles of Various Cell Populations

Figure 1. Staining Profiles of Various Cell Populations

(A) E18 cortical rat neurons were cultured using the NeuroCult™ SM1 Neuronal Culture Kit on poly-lysine-coated glass coverslips, then fixed and labeled with Anti-Beta-Tubulin III Antibody, Clone AA10, Alexa Fluor® 488 (Catalog #60100AD, green), and counterstained with DAPI (blue). Inset shows cells incubated with a mouse IgG2a, kappa isotype control antibody, Alexa Fluor® 488, and counterstained with DAPI. (B) Imaging flow cytometry analysis of human peripheral blood mononuclear cells (PBMCs) labeled with Anti-Human CD45 Antibody, Clone HI30, PE (red, Catalog #60018PE) and counterstained with DAPI (blue). Staining of a non-viable leukocyte is shown in the top panel and staining of a viable leukocyte in the bottom panel. (C) Chemical structure of DAPI (Hydrochloride).
