West Nile Virus (WNV)

ID Screen® West Nile IgM Capture


IgM Antibody Capture ELISA (MAC) kit for the detection of anti-prE IgM antibodies in horse serum and plasma.

The detection of IgM antibodies indicates recent infection and WNV circulation.





  • Sensitive and specific detection of WNV IgM antibodies, indicators of recent infection
  • Rapid and convenient: all reagents are supplied ready-to-use, samples are diluted directly in the plate (no pre-dilutions required), and all reagents may be transported at room temperature and stored at 4°C
  • Practical: you can easily check that all samples have been correctly deposited because the dilution buffer changes color upon addition of the sera
