Used in immunological research to quantify levels of SOCS-1 protein in biological samples such as cell lysates, serum, or plasma. SOCS-1 plays a key role in regulating cytokine signaling pathways, particularly those involving JAK-STAT, making this kit valuable for studying immune regulation, inflammation, autoimmune diseases, and cancer. Researchers use it to assess how SOCS-1 expression changes under different experimental conditions, including drug treatments or pathogen exposure. The kit enables high-throughput analysis with high specificity and sensitivity, supporting both basic research and biomarker validation studies.
