Re: [Histonet] Superfrost plus gold slides vs superfrost plus

2009-06-19 Thread Peggy Bisher
I had a group here who were having trouble with their cryo-sections sticking to the slides. Their samples were rat brains. He found that the Gold Super Frost Plus worked well with in-situ but not for immuno. At least that is the comment he wrote down and put on our bulletin board in the lab. Most

2009-03-31 Thread Peggy Bisher
Hi Histonetters, I have someone here who is having problems with their samples (mouse lung and mammary). It appears that the sample is very brittle when she cuts and in addition, some of the paraffin around the sample in the cassette is very white in color instead of the normal translucent color.

Actually I had a project to find bacteria in the ovaries of drosophila. The bacteria looked a lot like mitochondria and about the same size. That was a lot of fun, but at least I got to use a TEM for the imaging. You could barely see the sample in the dissecting microscope and it was only after I

We have a bottle of it here in the lab. It came from Acros, which means we ordered it from Fisher Scientific. Maggie On 2/25/09 11:30 AM, Janice Mitchell mitchel...@email.chop.edu wrote: Hi histoland, Anyone out there using canada balsam? If so where are you purchasing? Thanks in advance.

Liquid nitrogen (-196C) and nitrogen slush (-207) are the coldest cryogens used, but they have the slowest freezing rates. The most effective cryogens are those that are those that stay a liquid when cooled almost to the temperature of liquid nitrogen. Propane (-189.6C mp) or Ethane (183.5C mp)

Actually I belong to the MSA and they have a place on their web page to list equipment for sale. If you know exactly what you have, then that would be the way to go. You will have to join though, to post it. It doesn't cost anything to join, just some information. Margaret E. Bisher Electron
