Used in biomedical research to measure histone deacetylase (HDAC) activity in rat samples, this ELISA kit enables scientists to quantify HDAC protein levels in cell lysates or tissue extracts. It is widely applied in studies related to epigenetics, gene expression regulation, and cellular differentiation. Researchers also use it in investigating diseases such as cancer, neurodegenerative disorders, and inflammatory conditions where HDAC activity is altered. The assay provides a sensitive and specific method for evaluating the effects of HDAC inhibitors or other therapeutic compounds in preclinical animal models.
