Used in epigenetic research to detect and quantify citrullinated histone H3 in rat samples, particularly in studies related to cell death mechanisms such as NETosis (neutrophil extracellular trap formation). Widely applied in immunology and inflammation research to investigate the role of histone citrullination in autoimmune diseases, sepsis, and other conditions involving excessive or dysregulated cell death. The kit enables researchers to measure levels of this specific histone modification in tissue homogenates or cell lysates, providing insight into chromatin remodeling and gene regulation processes in disease models.
