Used in biomedical research to quantify levels of p38 mitogen-activated protein kinase in cell or tissue samples. Helps study cellular responses to stress, inflammation, and apoptosis. Commonly applied in drug development to evaluate the effectiveness of anti-inflammatory or anti-cancer compounds targeting p38MAPK signaling pathways. Enables researchers to monitor activation states of p38MAPK through detection of phosphorylated forms. Widely used in academic labs, pharmaceutical research, and clinical studies investigating diseases like arthritis, neurodegenerative disorders, and cardiovascular conditions.
