Foot-and-mouth disease virus (FMDV) Non-structural protein 

Antibody 3ABC ELISATest Kit

1. Principle

Foot-and-mouth disease virus (FMDV) Non-structural protein Antibody 3ABC ELISA Test Kit is suitable for test serum of cattle, sheep, goats and pigs, it can distinguish between immunized animals and wild-infected animals.

This kit use block ELISA method, FMDV-3ABC antigen is pre-coated on enzyme micro-well strips. When testing, add diluted serum sample, after incubation, if there is FMD virus specific antibody, it will combine with the pre-coated antigen, discard the uncombined antibody and other components with washing; then add enzyme labled anti-FMD virus monoclonal antibody, antibody in sample block the combination of monoclonal antibody and pre-coated antigen; discard the uncombined enzyme conjugate with washing; Add TMB substrate in micro-wells, the blue signal by Enzyme catalysis is in inverse proportion of antibody content in sample, use ELISA reader at 450nm wavelenth to measure the absorbance A value in reaction wells after adding stop solution to stop the reaction.

2.Reagents and contents









FMDV-3ABC AgCoatedplates 96 wells

2 plates


Stop solution

15 ml





Negative control

2 ml


10XConcentrated Washing buffer 

100 ml


Positive control

1 ml



22 ml


Adhesive Foil

4 pieces


Sample diluent

100 ml



1 piece


3.Materialrequired notprovided

1) Micropipette: 10ul-100ul, 100ul-1000ul.

2) Disposable pipette tips.

3) Graduate: 500ml.

4) Microplate Reader: 96 wells with 450/630nm wavelength.

5) Distilled water or deionized water.

6) Bottle washer or Microplate Washer

4. Sample preparation

Take animal whole blood, get serum by using regular method, the serum should bright and no hemolysis

5. Washing buffer preparation

Return 10X Concentrated washing buffer into room temperature before use, if there is salt crystals, shake to make it dissolved, then dilute it at 10 times with distilled water or deionized water. The diluted washing buffer can store at 4℃for about 1 week.

6. Notes

1) Return all reagents into room temperature before use, put the reagents at room temperature for at least 1 hour. Shake it evenly before use, and store back to 2-8℃after usage.

2) Do not mix use reagents from different kits and different lot no., prevent the reagents been polluted when using.

3) Substrate and stop solution may have irritation to skin and eyes, be careful to use.

4) Do not expose Substrate to strong light and avoid contact with the oxidant.

5) FMDV-3ABC Ag coated plates should be sealed and moisture-proof. Put back unused Micro-Well plate into dry foil bag and sealed at 2-8 ℃.

6) All wastes should be treated well to avoid pollution before discarding.

7) Strict compliance with the operating instructions can get the best results. Pipetting operation, timing, and washing of the whole process must be precise.

8) FMDV-3ABC Ag Coated plates is disposable, do not repeat use.

7.Test procedure

1) Take the antigen coated plate(the plate can be open and used for several times according to sample quantity each time), for every test, set 1 well for positive control and 2 wells for negative control, positive control and negative control do not need dilute, take 100ul directly and add into its well;

2) Add Sample diluent to reaction wells, 80ul/well, then add serum sample to the reaction wells, 20ul/well, blow and mix evenly(Do not mix use tips)

3) Cover it with Adhesive Foil, react at 22 (±3℃) for Overnight (about 16-18 hours);

4) Open the adhesive foil, discard the liquid of the well, add diluted washing buffer to each well, 250ul/well, then discard the liquid, repeat the above step for 6 times, at last flap to dry with the absorbent paper;

5) Adding Enzyme Conjugate 100ul/well, Cover it with Adhesive Foil,incubateat 22 (±3℃) for60 minutes;

6) Open the adhesive foil, discard the liquid of the well, washing for 6 times as step 4), remember at last flap to dry with the absorbent paper;

7) Add substrate, 100ul/well, mix it evenly then cover it with Adhesive Foil,incubateat 22 (±3℃) in darkfor15 minutes;

8) Add stop solution 50ul/well to stop the reaction, measure the result in 10 minutes.

8. Results judgment

Read the OD value with ELISA Reader at 450nm (630nm as reference).

For the assay to be valid:

Negative control (N) OD value > 0.6 , meanwhile positive control (PI) blocking rate > 50%;

Calculate method:

PI(blocking rate) = 1 - (Sample OD value/Average OD value of Negative control)


PI(blocking rate) > 50%: Positive

PI(blocking rate)≤50%: Negative

9. Storage and expire date

Store at 2~8℃ in dark, no frozen, expiry date: 12 months.
