Whole-mount immunofluorescent staining facilitates the profiling of protein expression patterns within diverse and complex tissues. Thanks to the application of antibodies on whole mounted instead of sectioned specimens, this technique has many advantages with respect to the preservation of biological and pathological features of specimens when compared to conventional immunohistological methods. Here, we describe a protocol and optimal conditions of whole-mount immunofluorescence for studying the formation of mammary primordia. We also show an example three-dimensional reconstruction of a mammary primordium based on z-stacked images of a whole-mount stained specimen using confocal microscopy and image analysis software.
