Fwd: Re: Fixation buffer.
From: | "Dr. Ian Montgomery" |
Adrian,
Measure
Sorensen's standard buffer with an osmometer, although physiological it
does have a high osmolarity, that's why I thought it might work. Yes,
I've started trawling through the journals etc. looking for the
"standard" sea water substitute. As for the Clyde, well, if the
cold and rain don't get me the pollution certainly would.

Ian:
Sorensen buffers are physiological strength aren't they, and so somewhat
hypotonic to sea-water? There are a number of recipes for
artificial sea waters in older biochemistry books, and I would have
thought any of them would work as a base for making up the
fixative. I may be able to dig some out if you need me to. In
this weather, it would be more comfortable than going down to the Clyde
to dip a bucket in.
Good luck,
Adrian Leek.

Preparing
fish larvae (sea) for EM, any suggestions for a suitable buffering system
given that the levels of salt in sea fish are ~3 times that of
mammals. Do I simply make up the fixatives using sea water? Sorenson
buffered fixatives have a high osmolarity that might be another buffer.
Time, unfortunately, is short so I can't run a series of trials although
I would prefer that.
Back to
mammals, lymphocytes and macrophage in mice, any suggestions. I was going
to look for esterases as a marker for macrophage but I'm sure there is
something better.
