WSE-7130 EzFluoroStain DNA
Purpose and Application
- Fluorescent dye for detection of DNA in post-electrophoresis
- More safety compared to EtBr
Features
- Higher sensitive detection of DNA with the lower ground as compared with EtBr (Ethidium Bromide）
- Detection with UV or BlueLED
- BlueLED enables to detect DNA bands with higher sensitivity and safety
- More safety compared to EtBr
- Lowest value by Ames test, not containing the carcinogenic substance of IARC
- Unnecessary for destaining step, speedy, small amount of waste fluid
