Used in immunological research to quantitatively measure rat mannose receptor C1 (MRC1) levels in biological samples such as serum, plasma, tissue homogenates, and cell culture supernatants. This ELISA kit is particularly valuable in studies related to macrophage activation and polarization, as MRC1 is a marker for anti-inflammatory M2 macrophages. It supports research in inflammation, infectious diseases, cancer, and autoimmune disorders by enabling accurate assessment of MRC1 expression in rat models. The assay helps evaluate immune responses and monitor the effects of therapeutic interventions in preclinical studies.
