Used in biomedical research to quantify Macrophage Stimulating Protein (MSP) levels in biological samples such as serum, plasma, and cell culture supernatants. The kit enables researchers to study MSP's role in inflammation, tissue repair, and cancer progression by providing a reliable and sensitive method for detecting MSP concentration. It is widely applied in immunology and oncology studies to investigate macrophage activation, tumor microenvironment interactions, and disease biomarker discovery. The assay supports high-throughput analysis and is essential for preclinical research involving signaling pathways related to the RON receptor tyrosine kinase.
