If you are using an inverted scope then the areas close to the bottom are less affected by spherical aberration and scattering. That's why they should be brighter.

Subject: Strange artifact in z series
Search the CONFOCAL archive at
http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocalHi all,
while performing z sections of mitochondria-stained living cells, I´m
finding that the bottom part of the cell displays a brighter mitochondria
fluoresecence, showing more contrast respect to cytosol than mitochondria in
the top part of the cell. My system scans z from bottom to top. If it were
simple bleaching due to laser light passing through the cell, I should
observe that the bottom mitochondria are also less stained in a second
series, but that´s not the case (the difference between top and bottom still
there)
Any idea to explain it?
Thanks
Pedro
