Used to measure mouse macrophage colony-stimulating factor (M-CSF) levels in biological samples such as serum, plasma, and cell culture supernatants. It is widely applied in immunology and inflammation research to study macrophage activation, differentiation, and function. Commonly used in studies related to autoimmune diseases, cancer, bone metabolism, and infectious diseases where M-CSF plays a regulatory role. The kit enables sensitive and specific quantification, supporting both basic research and preclinical evaluation of therapeutic agents.
