It was always policy in other labs where I worked to never leave tissue in molten paraffin any longer than was needed for proper infiltration. We did, however, often remove them and let sit/harden at room temp. if we couldn't get to them right away and then we would put them in the embedding center to melt when ready to embed.

Subject: Holding tissues in paraffin

I'm very interested, if someone is really doing this. We recently, quit working Saturdays, a couple months, ago and are holding our tissues in formalin, for 2 nights. I like the idea of holding the tissues in paraffin and better yet, to pull them out, after the overnight run and reheat them, when it is time to embed them. Any suggestions or comments.

Thanks,
