I'm trying to load an AM-ester dye in an acute hippocampal brain slice. I am specifically interested in microglia (which are GFP labelled), however, I understand that microglia are particularly difficult to image with these dyes.
We recover for 1 hour in aCSF at room temperature after slicing, then I will incubate with the dye (containing DMSO and diluted in aCSF) at room temperature for 30 min.
Does anyone have tips for getting AM-ester dyes into microglia?
Thanks!
