C3H cells (murine embryo fibroblasts). Dye is Lucifer Yellow CH (or any other dye used for Gap Junctions if you know any one else...)
Besides, it seems petri dishes plastic has some kind of background noise when it comes to fluorescence. I've done immunofluorescence before, but only on glass coverslips.
Purpose of the experiment is to observe the status of the gap junctions while a drug treatment is being done.
2 dumb questions:
1) it can only be done on single layered cells, not con multilayered colonies, right?
2) what microinjector do you use?
tnx!!
