FMDV 3Diff/PAN Ag Combo Test Kit



Foot-and-mouth disease virus (FMDV) causes an acute vesicular disease of cloven-hoofed animals and continues to be a threat to livestock worldwide with outbreaks causing severe economic losses.
The RIDX® FMDV 3Diff/PAN Ag Combo Test Kit is a lateral flow chromatographic immunoassay for the qualitative detections of all seven (7) serotypes antigens of FMDV in bovine or porcine samples.
• 3Diff Ag Test: FMDV 3Diff detects FMDV Asia1, type A, and type O antigens. Three test lines (AS, A, O) and the control (C) line on the surface of the device.
• PAN Ag Test: FMDV PAN detects all 7 serotypes (type O, type A, type C, Asia1, SAT1, SAT2, and SAT3) of FMDV antigens. The test line (PAN) and the control (C) line on the surface of the device.
If the FMDV antigens exist in the sample, that bind to the gold-conjugated FMDV antibodies. The complexes move through the membrane by capillary force and respond to the FMDV antibodies on the test line, resulting in a red line. The control line indicates that the test is performed correctly.
The highly selective and sensitive four monoclonal antibodies to FMDV are used as capture and detector in the RIDX® FMDV 3Diff/PAN Ag Combo Test Kit. These antibodies are capable of detecting FMDV antigens in bovine and porcine samples with high accuracy.

• 10 Tests/Kit


1. All reagents and samples must be at room temperature (15~30℃/59~86℉) before use.
2. Take the supernatant of the prepared sample solution by using a dropper.
3. Add 4 drops (100μL) of the sample solution into each sample hole on the test device slowly and vertically.
4. Read test results at 15 minutes.
