Re: [Histonet] Image Analysis
The intensity of DAB staining does not usually
indicate the quantity or concentration of an
antigen in an immunoperoxidase section. There
are even circumstances in which the amount of oxidized
DAB can vary inversely with the local concentration
of the antigen. In general: enzyme amplification
can detect and localize very small amounts of
some antigens, but the intensity of staining has
no quantitative significance.
There is a large body of peer-reviewed literature
in the field of quantitative immunohistochemistry.
Optical measurements correlate with antigen
concentration only with the simplest methods.
