Used in immunological research to quantify Protectin D1 (PD1), a specialized pro-resolving lipid mediator derived from omega-3 fatty acids, in biological samples such as serum, plasma, and tissue homogenates. The kit enables researchers to assess PD1 levels in mouse models of inflammation, helping to study its role in resolving inflammatory responses, tissue protection, and immune regulation. Commonly applied in studies related to inflammatory diseases including asthma, arthritis, colitis, and neurodegenerative conditions, where modulation of inflammation and promotion of tissue repair are key. The assay supports high sensitivity and specificity, allowing accurate measurement of PD1 concentration to evaluate the effectiveness of therapeutic interventions targeting inflammatory pathways.
