Used in immunological research to quantify levels of colony stimulating factor 1 receptor (CSF1R) in biological samples, this ELISA kit enables scientists to study macrophage differentiation, survival, and function. It is particularly valuable in inflammation, cancer, and autoimmune disease studies where CSF1R signaling plays a key role. The assay supports high-throughput screening and therapeutic development by providing a reliable method to monitor CSF1R expression and evaluate drug effects on the CSF1/CSF1R pathway.
