Used in epigenetic and immunological research to detect and quantify citrullinated histone H3 in rat samples, particularly in studies related to neutrophil extracellular trap (NET) formation, a process involved in innate immunity and inflammation. This kit is valuable in researching conditions such as sepsis, autoimmune diseases, ischemia-reperfusion injury, and other inflammatory disorders where histone citrullination plays a regulatory role. By enabling specific measurement of citrullinated H3, it supports investigation into the mechanisms of chromatin decondensation and NETosis in experimental models.
