Used in biomedical research to quantify levels of USP2a protein in cell lysates or tissue samples. Helps study the role of ubiquitination in cellular processes such as protein degradation, DNA repair, and signal transduction. Commonly applied in cancer research to investigate USP2a overexpression in tumors, particularly prostate and brain cancers. Enables evaluation of USP2a as a potential biomarker or therapeutic target. Supports drug development by monitoring USP2a activity in response to inhibitors or experimental treatments. Suitable for high-throughput screening in preclinical studies.
