Used in immunological research to quantitatively measure CXC chemokine ligand 20 levels in biological samples such as serum, plasma, and cell culture supernatants. Helps in studying inflammatory responses, immune cell recruitment, and chemokine signaling pathways. Commonly applied in research related to autoimmune diseases, cancer immunology, and infectious diseases to understand the role of CXCL20 in disease progression and immune regulation. Provides high sensitivity and specificity for accurate detection, supporting biomarker validation and therapeutic development.
