Introduction:

Foot and Mouth Disease (FMD) is an acute, febrile, highly contagious disease of cloven-hoofed animals caused by the Foot and Mouth Disease Virus (FMDV). It is characterized by the formation of vesicles and erosions on the oral mucosa, feet, and mammary skin.

This assay is designed to detect antibodies against the against the non-structural protein 3ABC of foot-and-mouth disease (FMD-NSP) in porcine serum or plasma. Suitable for screening and auxiliary diagnosis of FMD wild-type virus infection

Principle :

This kit comprises a coated Microtiter Plate with FMD-NSP antigens, HRP conjugate, and other accompanying reagents. It employs the principle of enzyme-linked immunosorbent assay(ELISA) to detect antibodies against FMD-NSP in the porcine serum or plasma. During the experiment, control serum and test sample are added to the plate. After incubation, if the sample contains FMD-NSP antibodies, they will bind to the antigens coated on the microtiter plate. Following washing steps to remove unbound components, the HRP conjugate is added, which specifically binds to the antigen-antibody complexes on the plate. After washing again to remove unbound HRP conjugate, substrate reagents are added to the wells and react with the enzyme-labeled complexes, resulting in a blue color. The intensity of the color is directly proportional to the amount of specific antibody present in the sample. The reaction is then terminated by adding a stop solution, turning the solution yellow. The absorbance of each well is measured at a wavelength of 450nm using a microtiter plate reader (microplate reader) to determine the presence of FMD-NSP antibodies in the sample.
