Preparation of Sample Staining Solution1. Dissolve 9 mg DAB with 1 ml PBS to prepare 100X DAB solution.2. Mix 5 μl of 30% hydrogen peroxidase solution with 1 ml PBS to prepare 200X H2O2 solution.3. Add 10 ul of 100X DAB solution and 5 ul of 200X H2O2 solution to 1 ml PBS to prepare staining solutiona).4. Add the staining solution to a sample in a staining chamber, and incubate the sample at room temperature for 5 minutes to 1 hourb).5. Wash the sample with PBS several times to stop the staining reaction.
a)The staining solution is not stable. Prepare fresh solution prior to use.b)For better staining, incubate the sample with 0.09 mg DAB/PBS solution for 10 minutes before adding the staining solution.

Cell Staining Redox Dyes
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。
