Fwd: EM Staining cont...
Sara,
fine
needles - Uranyl salt. Cannon balls - lead. Are you staining en
bloc or sections on grids. Apart from the dirty staining and I know
you've probably thought about it, poor contrast - objective
aperture.

Sorry, message was prematurely sent before completion.
As I was saying, the methelene UA and Sato's lead citrate are utilized in
a Pelco Microwave. Until the last week, our microwave staining has been
very good and problem free. I want to know if humidity plays a big part
in microwave staining. Also, does black precipitate on the section always
denote that the lead stain was poorly rinsed or has gone bad? Lastly,
what can be done to combat/correct poor contrast. Please feel free to add
additional comments that were not specifically addressed in this message.
Thanks!
