Used in biomedical research to quantify MaR2 (Maresin 2), a specialized pro-resolving lipid mediator, in biological samples such as serum, plasma, or tissue homogenates. Enables investigation of MaR2's role in inflammation resolution, tissue repair, and immune modulation. Commonly applied in studies related to inflammatory diseases, including arthritis, lung injury, and gastrointestinal disorders. Supports research into metabolic diseases and neuroinflammation by providing a reliable method to measure endogenous MaR2 levels during disease progression or therapeutic intervention.
