RE: nonspecific staining on neg. controls w/EDTA
|From:||"Favara, Cynthia (NIH/NIAID)" |
My first question would be ...what quality control do you have for your EDTA
Do you have limits for temperature/time and is it monitored?
Is the EDTA pH checked? How often?
You probably have addressed these issues!
Just a place to start.

Subject: nonspecific staining on neg. controls w/EDTA
I have been having difficulty trying to figure out why we occasionally have
nonspecific staining on our negative controls when we use EDTA for HIER. It
is not on any specific type tissue - we've had staining on skin, thyroid,
ect. We haven't changed any of our methods, but this has just cropped up as
a problem within the last month or so. Any suggestions?
Thanks in advance,
