Dear bob1,
Thank you for getting back to me. At which step do you suggest doing this wash? I am doing fixation overnight when I collect the tissue, and then there are two more fixation steps in my protocol (already after the deparaffinization steps).
Best,
Maya

Dear Curtis,
Thanks, I did that on the same day as I posted this question. Also got some replies and will try the one they have! Hopefully it works...I'll report back!

Hi all *waves*,
I am Maya and I am a 1st year PhD at Cambridge. My first year report submission deadline is just ahead...I love research but I also hate it. I guess it's a bit like with Gollum and the ring, lol.
Anyway, I am quite new to the forum and thought I'd introduce myself...
Have a nice day,

In Topic: ISH - signal in sense - specificity or contamination problem?
11 July 2012 - 05:55 AM
Hi alexa594,
I have not left the liver S overnight so I can't be 100% sure that I wouldn't have ended up with some background there, too. However, none of the slides which I left incubated overnight dried out (at least not obviously so) - when I stopped incubation the next morning, all of the sections were still completely wet (I circle with pap-pen and actually add 400ul of hyb buffer with probe to each section). So I am quite sure this is not simply unspecific background due to drying out of sections, especially since both AS and S seem to selectively stain specific cell types only within the tissue of interest.

Hi Montys,
I am not sure if you are still waiting for an answer to your question. I am doing ISH and I am also experiencing some problems. Did you check that the probe you are using is specific to mouse? If it is a probe designed for a rat gene, that might be the reason it doesn't work in mouse?
Best,
Maya
