Since immunofluorescence intensity is generally proportional to Ag density
if one carefully controls the staining conditions - what is the
proportionality?
Unless otherwise stated, proportional implies a direct or linear relationship.
This would hold for MAbs directly labeled with a single fluorochrome (FITC),
but what about phycobiliproteins? Or streptavidin conjugates? For a MAb
conjugated to PE wouldn't the relationship of fluorescence to Ag density be
geometric?
