No Wash FISH
Microscopy
First I'll test whether the samples can be taken directly to the microscope, with the hybridization buffer still on. This will produce a higher background noise, but will hopefully still result in strong areas of signal distinguishable from the background. Since this is just a test, I'll only use the positive control (sample D, Cot1-488) for now, and I'll investigate the others pending successful trial.

As expected, the background is definitely higher, but the signal is also stronger. It will be interesting to do a wash on these samples, and then examine them after. Given the success, I'm going to return the positive control to the incubator and I'll take snapshots of the other 3 samples.
