Used in research and diagnostic applications to detect and neutralize the Middle East Respiratory Syndrome coronavirus (MERS-CoV). It serves as a critical tool in immunoassays such as ELISA, Western blot, and immunofluorescence to confirm the presence of MERS-CoV antigens. Due to its high specificity, it is employed in evaluating immune responses and in the development of therapeutic antibodies and vaccines. It also acts as a control in neutralization assays to assess the efficacy of candidate treatments against MERS-CoV infection.
