I am using Cyclin E from NeoMarkers(Labvision) with a placental control. I do
see the nuclear staining that is a true positive but I am also seeing a fairly
good amount of cytoplasmic staining as well. I have titrated this antibody out
until there is no staining at all as well as running a negative control(which is
beautifully clean). Has anyone else seen this and if you have how have you
treated this? I am using LSAB+ kit from Dako with DAB.
I'm also looking for ways to get rid of background on human kidney. I have
avidin/biotin blocked for 15 minutes each but the negative control still has
very specific background. Should I switch to an alk phos system?
