Re: Macrophages + 25F9, 27E10 and RM3/1
We use the antibody to look at gross numbers of macrophages in bacterial
infected gastric tissue versus non-infected controls. So we haven't really
looked at the individual cell morphology. The 'infected' tissue macrophages
themselves do appear larger and more 'macrophage' like, but this tends to
result in more difficulties in cell counting, we just count relative stained
area of tissue to compensate.
The cells themselves stain variably. Some are beautiful, others have a patchy
staining with the stain localised to one side of the nucleus.
We have also tried several other antibodies which are supposed to stain at
various stages of activation:
25F9, 27E10 and RM3/1 from Dianova Germany.
They do stain a specific subsets of the CD163 positive cells, but I have a
problem with non-specific and background staining. Don't suppose anyone else
has any experience with these antibodies?
