Image Analysis System for Quantitative Immunofluorescence Measurement
Immunofluorescence methods for hormone-containing cells exposure are widely used but the quantitative nature of the immunostaining is frequently ignored. In this study, quantitative measurements of fluorescent pancreatic beta-cells before and after glucose stimulation were used to determine parameters characterizing insulin synthesis and secretory activity. Beta-cells in Wistar rats pancreatic islets were stained using indirect immunohistochemistry, with subsequent processing on image analysis systems. The presence of three independent beta-cell classes with different insulin synthesis and secretion activity was shown by subsequent cluster analysis and confirmed by changes in insulin blood level.
