Immunolabelling Myofiber Dégénérescence dans les biopsies musculaires

Overview

This study presents a protocol for the immunolabelling of necrotic myofibers in muscle cryosections, addressing the critical issue of myofiber necrosis in various neuromuscular disorders. The method utilizes immunoglobulin G (IgG) uptake to identify and quantify necrotic cells, providing meaningful insights into muscle degeneration.
