Used in biomedical research to quantify levels of CXCL16, a protein involved in immune responses and inflammation. Helps in studying diseases such as atherosclerosis, liver disease, and cancer where CXCL16 plays a role in cell signaling and recruitment of immune cells. Commonly applied in serum, plasma, and cell culture supernatant analysis to support diagnostic development and therapeutic monitoring. Enables researchers to evaluate the impact of treatments on inflammatory pathways in preclinical studies.
