This protocol can be used with formalin-fixed paraffin-embedded (FFPE) sections for the staining of two to six antigens per slide depending on the slide scanner available in the laboratory. Medicine Fiber Type and Subcellular-Specific Analysis of Lipid Droplet Content in Skeletal Muscle Camille M. Selvais1, Laura L. De Cock1, Sonia M. Brichard1, María A. Davis-López de Carrizosa1,2 1Endocrinology, Diabetes and Nutrition Unit, Institute of Experimental and Clinical Research, Medical Sector, Université Catholique de Louvain, 2Departamento de Fisiología, Facultad de Biología, Universidad de Sevilla Increasing evidence indicates that excessive infiltration of lipids inside skeletal muscle results in lipotoxicity and diabetes. Here, we present a complete protocol, including tissue processing, staining with Bodipy, image acquisition, and analysis, to quantify the size, density, and subcellular distribution of lipid droplets in a fiber-type specific manner.
