Dr Cartun-
We've had similar experiences to Hugh's. In the histo group we maybe only have
15 validated freezers (all Revco's), but throughout our company we have
hundreds. Over the past few years our Research Operations has moved to
purchasing Sanyos because of the turnover rates of the new ultra low Revco's.
We have no Sanyo's in our group yet, so I do not have any feedback on their
performance. (I've always used uprights, so I'm not much use there either.)
Best of luck!

Dr. Cartun,
Agreed, chest freezers have less frost/door problems/sealing issues and seem to
live longer. Stand-ups maximize footprint/space efficiency and allow for
easier, horizontal-rack pulling for archiving and inventory. Due to volume and
space constraints, the UH cancer center buys stand-ups. We have over a hundred.
My personal caution is for the newer Thermo-Revco freezers, especially the
ultra-low Thermo UXF in mostly 24.1 cu. ft.. Perhaps this is just our bad luck
but an abnormal number failed (7/9), and three were within the first year. The
unfortunate units were purchased over the last four years. Our bio-engineer
has asked us to avoid buying Revco (after endorsing Revco/Harris for many
years) and buy New Brunswick/Eppendorf or Sanyo ULT freezers, for the immediate
future.
We're not endorsing Sanyo or New Brunswick, we're just staying away from a
brand that has recently given us trouble. Hopefully, it is different in your
area, as Hawaii has logistical issues that may have exacerbated this issue
(maybe it was that looong boat trip)?
Just my $0.02. (And $0.02 will not buy anything, anymore.)

We have both upright and chest and both have their pros and cons. We have had
trouble with electrical circuits which aren't matched to the load that these
freezers can put on them. An electrician told us that it can put an tremendous
strain on the freezer motor if the circuit isn't right and two or three
freezers start up at the same time- leading to shortened life of the freezer.
So- make sure a good electrician is involved in your freezer set-up. Tom T

Hi Everyone.
I am looking to stain alcohol fixed smears with a group of antibodies.
The antibodies of particular interest are p63, p53 and ki67.
Along with these antibodies I am looking for positive nuclear and cytoplastic
staining antibodies.
If anyone has any experience in staining alcohol fixed slides your information
is very appreciated.
All the best.

Sincerely,
- Levi Fried
