Used in biomedical research to quantify levels of ubiquitin-specific protease 40 (USP40) in cell or tissue samples. Helps study the regulation of protein degradation pathways, particularly the ubiquitin-proteasome system. Applied in investigating diseases linked to protein homeostasis dysfunction, such as neurodegenerative disorders and cancer. Enables researchers to monitor USP40 expression under experimental conditions, assess the impact of drug treatments, and validate gene knockdown or overexpression effects. Provides a reliable, high-throughput method for protein detection in lysates and biological fluids.
