Dear Connie,
Hey, don't take it all so seriously, we all tend to generalise sometimes!
It's great to hear about folks' outside interests and I congratulate you on
being an accomplished musician. I tend to aggree with you about Mendelsohnn
and Mozart, but as a limey, I also like Elgar who is one of my heroes.
By the way, I use Gill's No 3.
Have a good wednesday. I shall be going home to do some gardening in just
over an hour - one of my hobbies.
Regards
margaret

Is Gill a relative or yours??? I don't give a hoot who made what when.
I like Harris. I don't believe Gill has made any significant
improvements over the old dead white guy's hematoxylin.
BTW, classical music may have been composed by dead white guys, but I
don't hear ANYTHING being composed today that has the depth, complexity
and color of those great composers. I've studied piano from since I was
4 yrs old, and I've studied the organ (I've played as a church
organist)for almost 20 years. I know music like the back of my hand
and I love ALL music (except gangstah stuff). SO DON'T try to tell me
about what music is living and worth my while.
Dead white Europeans. Yeah, right. I'd like to see someone between 8 and
14 in this generation compose music like Felix Mendelsohnn's or
Mozart's.

You may have heard that classical music was composed by dead white
Europeans. Well, Harris hematoxylin was composed by a dead white
American
(physician at Jefferson Hospital in 1904). Gill hematoxylin was
composed by
a live white American. So if you want to liven things up, go with
Gill's!

Wow. What a lot of interesting comments!!
I agree with Terry re the agitation. When I watch the stainer do those
dips
(I can program how many, but NOT the briskness), I wonder if you could
even
call it agitation. My hand dips are very brisk. Also, I don't bother
letting the slides stay in the alcohols for 1 minute or 2, I give the
slides
about 20 -30 good brisk dips in each solution, then the timed rinses &
staining. This has always been far more satisfactory to me than those
sllllooooowwwww dips from the machine.
As for the kind of hematoxylin, someone suggested I throw out the Harris
and
do Gills III. I've tried Gill III before and I much prefer the Harris.
So
it's just a matter of personal preference on that... AND what your
pathologist likes *G*
Everyone having an nice Tuesday??? *g*

Connie remarks:
"In truth, I prefer my hand stained sections better than when they're
stained automatically."
When I first saw what I call x-y stainers, I thought that we had in
this,
something that reproduced hand staining. Not so. What I think is lacking
is
the brisk agitation necessary to break down the interface between old
and
new solution. I'm not so sure about the rinsing either.

We use almost the exact same protocol... we use Surgipath Harris, but we
prepare eosin in-house. One thing I am amazed at in this protocol is
the
length of time in the acid alcohol. Do you use an autostainer? We have
a
Leica. The time is set to 1 second in the acid ETOH and
sometimes the sections are almost too differentiated. I can't imagine
6 seconds in the acid ETOH!! Even when I do H&E manually, I dip the
slides
in and quickly put them in running water. I must have a very strong
solution, I guess. Hmmmm. Interesting. In truth, I prefer my hand
stained
sections better than when they're stained automatically.
Just wondering and blabbering (hey, it's Tuesday, what do you expect??)

Hi,
I use Harris's hematoxylin which is also regressive and purchase my
hematoxylin and eosin /alcohol-based/ from www.surgipath.com. I get very
good H&E staining with this protocol.
