I want to use the method of Single Cell Gel Electrophoresis (comet assay). I have many samples, but I don't have the appropriate microscope. So I have to preserve my slides until the time comes for staining and microscopic analysis. I've read many different protocols, and I can't decide which is the best. Also, after the staining and the analysis, I might need to reuse the same slide. Is that possible? and if yes, what should I do?
