Used in immunological research to quantitatively measure levels of the human mannose receptor in biological samples such as serum, plasma, or cell culture supernatants. This kit is particularly valuable in studies related to innate immunity, antigen presentation, and macrophage or dendritic cell activation. It supports research into infectious diseases, inflammatory conditions, and cancer immunology by enabling accurate detection of MR expression, which plays a role in pathogen recognition and immune response modulation. The assay is commonly used in biomedical laboratories and drug development settings to evaluate immune system behavior under various experimental or clinical conditions.
