Used in immunological research to quantify soluble cytokine receptors in biological samples such as serum, plasma, and cell culture supernatants. Helps in studying inflammatory diseases, autoimmune disorders, and immune system activation. Commonly applied in clinical research to monitor disease progression and response to therapy. Enables high-throughput screening in drug development and biomarker discovery. Provides a reliable and sensitive method for detecting receptor levels, aiding in the understanding of cytokine signaling pathways.
