DescriptionApplicationReferencesDataS.D.SProduct DescriptionDAPI is an AT-sequence specific DNA intercalator that attaches to DNA at the minor groove of the double helix like Hoechst dyes. Though DAPI is not permeable through viable cell membranes, it passes through disturbed cell membranes to stain the nucleus. DAPI has a high photo-bleaching tolerance level. DAPI is utilized for the detection of mitochondrial DNA in yeast, chloroplast DNA, virus DNA, micoplasm DNA and chromosomal DNA. The excitation and emission wavelengths of DAPI-DNA complex are 360 nm and 460 nm, respectively.Chemical StructureStaining Procedure1.Prepare 10-50 μM DAPI solution with PBS or an appropriate buffer.a)2.Add DAPI solution with 1/10 of the volume of cell culture medium to the cell culture.b)3.Incubate the cell at 37oC for 10-20 min.4.Wash cells twice with PBS or an appropriate buffer.5.Observe the cells using a fluorescence microscope with 360 nm excitation and 460 nm emission filters.a) Since DAPI may be carcinogenic, extreme care is necessary during handling.b) Or you may replace the culture medium with 1/10 concentration of DAPI buffer solution.1.

Dojindo细胞分析
细胞活力和细胞毒性测定用于药物筛选和化学物质的细胞毒性测试。Dojindo开发了高度水溶性的四唑盐，称为WST。WST-8是高度稳定的WST，用于Cell Counting Kit-8（CCK-8）。由于WST-8甲maz是水溶性的，因此不会形成晶体。因此，不需要诸如MTT测定的增溶过程。此外，CCK-8的检测灵敏度高于其他四唑盐，例如MTT，XTT，MTS或WST-1。
