Used to measure levels of CXCL16, a chemokine involved in immune responses, in biological samples such as serum, plasma, or cell culture supernatants. Helps in research on inflammatory diseases, atherosclerosis, cancer, and autoimmune disorders by providing a reliable method to quantify CXCL16 concentration. Enables scientists to study the role of CXCL16 in disease progression and immune cell recruitment. Commonly used in clinical research and drug development to evaluate biomarkers and therapeutic targets.
