Used to measure p38 mitogen-activated protein kinase (p38MAPK) activity in rabbit cell or tissue lysates. This assay is commonly applied in research settings to study cellular responses to stress, inflammation, and cytokine signaling. It enables researchers to quantify changes in p38MAPK phosphorylation and activity levels following drug treatments, genetic modifications, or exposure to external stimuli. Widely used in pharmacological and biomedical studies investigating pathways involved in inflammation, apoptosis, and immune regulation in rabbit models. Provides a reliable, sensitive, and high-throughput method for evaluating the effectiveness of kinase inhibitors or activators in experimental therapeutics.
