Manufactured by SafePath® exlusively for Centaur Animal Health, the FP-ELISA II Kit is Centaur’s third generation test for antibodies to Equine Infectious Anemia Virus in horse serum. Its name is derived from the Fusion of the p45 envelope antigen and the p26 core antigen used in the previous version. The protein is coated onto the plate and used in the conjugate. Equine antibodies to EIAV bridge the plate protein with the conjugate creating a highly sensitive and specific assay. During the redevelopment, Centaur took the opportunity to simplify and speed up the test. A new green conjugate helps the user monitor where it has been added or washed away.
