Used in immunological research to quantify levels of the CXCR4 chemokine receptor in mouse biological samples. This ELISA kit enables researchers to measure CXCR4 expression in cell lysates, tissue homogenates, and serum, supporting studies in inflammation, immune cell migration, and cancer metastasis. It is particularly valuable in preclinical studies involving mouse models of HIV infection, as CXCR4 acts as a co-receptor for viral entry, and in stem cell research due to its role in hematopoietic stem cell homing. The assay provides a sensitive and specific method for high-throughput screening in drug development and mechanistic studies of signaling pathways.
