Does anybody have experience/good advice on using the DAPI stain on fresh tissue (thickness between 0.5 and 1mm)? Concentrations, preparations, incubation time? Thanks so much!
I think you should not have any problem. We used to use DAPI nuclear staining in live whole-mount retina incubated in Ames medium at 34 degrees for about an hour (~1:2000). Incubation time, temperature and Dapi concentration may slightly vary among different tissues and also with age.
