Used in research settings to quantify levels of Macrophage Stimulating Protein beta (MSPβ) in biological samples such as serum, plasma, and cell culture supernatants. This kit enables scientists to study the role of MSPβ in immune regulation, inflammation, and tissue repair processes. It is particularly valuable in investigating diseases involving macrophage dysfunction, including chronic inflammatory conditions, autoimmune disorders, and certain cancers. The assay supports high sensitivity and specificity, allowing for accurate detection of MSPβ concentrations, which aids in biomarker validation and therapeutic development.
