Quantifying immunogold labelling in transmission electron microscopy.
Gold particles labelling on ultrathin sections is extensively used for antigen localization in transmission electron microscopy. In establishing absolute or relative counts in tissue sections, it would be expedient to use stereologically based unbiased estimates for quantitative results. Nowadays, quantitative immunoelectron microscopy has achieved good and satisfactory results to test whether the gold labelling follows a non-random or a random pattern and then to draw statistical comparisons between cell subcompartments within a sample of cells or between experimental groups of cells. This brief informal review of literature focuses on the relative quantitative determinations of gold labelling of antigens as well as on the statistical distribution comparisons in transmission electron microscopy.
