Immunogold quantification of the PMCA2 plasma membrane CaATPase pump. A, B Labeling of stereociliary bundles of apical and basal OHCs is greater than that of an IHC. C. Immunogold labeling of a section of gel impregnated with the PMCA2 peptide antigen. D. Immunogold counts for four different concentrations of antigen, measurements taken for the total area or for intersection of a line drawn across the section. The calibration was used to determine the pump density in hair cell stereocilia. Modified from (Chen et al., 2012).
