I can think of two things. First, relentlessly make fun of your building planner for putting a histology lab underneath a laundry. This is a mistake worthy of pointing and laughing. Second, there are isolation tables and platforms. That's probably the first thing I would try.

Currently my lab is using Aqua-mount (Lerner Laboratories). I'm looking at replacing it with a different Aqueous mounting media. The only stain we use it for is Oil Red O. I've tried many different variations on its use and the results have been the same. 1) The slide looks lovely the

Our lab uses 95% Ethanol. It takes longer to fix the tissue than formalin. But, it's effective and far less toxic than formalin. Gerry -Original Message- From: histonet-boun...@lists.utsouthwestern.edu [mailto:histonet-boun...@lists.utsouthwestern.edu] On Behalf Of Manahil Sent:

[Histonet] Covergrip

2015-01-30 Thread Keyser Gerald T
I would like to better seal my Oil Red O slides. The current process uses aqueous mountant on the inside of the large coverslips and Permount on the outside; which is incredibly messy and isn't actually that great of a seal. The two options I'm looking at is: 1) Nail polish. 2)

Voice to text cannot cope with doctors mumbling into recorders. Even the best VRS only hits about 95% of the regular dictionary; which is very good. But, a 5% error rate is wildly unacceptable in a clinical environment. Another parallel is trying to apply handwriting recognition software to a

I've only cut resin with a glass or diamond knife in an ultramicrotome. If you are attempting to do it in a regular microtome, you would need a special blade holder. I don't know if any microtome manufactures make glass knife holders. You make the glass blades yourself using special glass.

I'm toying with making my own aqueous mounting media. Although I will not likely use this in actual cases, it would still be nice. Aqueous mounting media is kind of expensive. But, there are some questions that need to be answered. The Slides need to be kept for 10 years. - Will the adhesive
