Used in research and diagnostic assays to detect the Middle East Respiratory Syndrome coronavirus (MERS-CoV). It specifically binds to the spike protein of MERS-CoV, enabling the identification and neutralization of the virus in cell cultures and clinical samples. Commonly applied in ELISA, immunofluorescence, and neutralization tests to evaluate immune responses and assess the efficacy of vaccines and antiviral treatments. Also serves as a control antibody in studies involving coronavirus pathogenesis and antibody development.
