描述 产品目录编号 124653 描述 4',6-DIAMIDINO-2-PHENYLINDOLE DIHYDROCHL 概述 4',6-Diamidino -2-phenylindole dihydrochloride is better known as "DAPI". It is a dry dye used for the preparation of a color staining solution that can be applied for fluorescence staining of DNA in nuclei in vivo or as counter stain in immunofluorescent methods in sample material of human origin.
The dye is a CE certified IVD product and has a constant dye content and a reliable high quality, which is one of the major precondition for a reproducible diagnostic staining.产品信息 CAS号 28718-90-3 EC号 249-186-7 Hill配方 C₁₆H₁₇Cl₂N₅ 化学配方 C₁₆H₁₅N₅*2HCl Molar Mass 350.25 g/mol HS代码 3204 19 00 结构配方图像 理化信息 熔点 330 °C (分解) pH值 4.0 - 5.0 (10 g/l, H₂O, 20 °C) 容积密度 120 kg/m³ 溶解度 (20 °C) 可溶 GHS安全信息 储存类别 10 - 13 其它液体及固体 WGK WGK 2 水危害 一次性 3
