Re: Sequenza Staining Racks!
Dear
Jennifer,
We have been using these racks as long as I remember (at least 10 years)
and have been very satisfied with them. You can do all the steps in the
racks (except for the incubation with DAB which we do here in a coplin
jar). For each antibody about 120 microliter is recommended but we
use 150 microliter. For the washing steps you just fill up the coverslips
with PBS from a squeezebottle. There is also no need to use the
disposable coverslips just once, after washing with water and some
detergent they can be re-used (do not wash them in the dishwasher because
then they will bend and cannot be used anymore). We use superfrost slides
but you can use als kinds of slides with the right dimensions.
Finally, one comment, somehow during the last years we are more and more
unsatisfied with the results from these racks; the stainings are often
uneven with strong staining on one side of the section and weak staining
on the other side. This however does not have anything to do with
the fact that we are re-using the coverslips, it also happens with a new
set of coverslips. We do not know the reason for this, it certainly is
not that the slides are not correctly fitted. I rather suspect that the
coverslips themselves somehow are manufactered differently. Does someone
else also has this experience?
