Avian Infectious Bursal Disease virus VP2 antibody

(IBDV-VP2 Ab) ELISA kit

Catalog No. LSY-30014

1. Introduction

This kit is used to detect Avian Infectious Bursal Disease virus Neutralizing antibody in chicken serum, to assess antibody condition by Avian Infectious Bursal Disease virus VP2 vaccine in chicken farm and assist diagnosis of serological infected chicken.

Chicken infectious bursal disease virus VP2 protein has a conformational (discontinuous) neutralizing antigenic determinant. Studies have found that antibodies against this antigenic determinant can passively protect chickens from infectious bursal disease virus infection.This kit use competitive ELISA method, composed by the reaction Micro-plate coated with high purity IBDV-VP2 antigen, horseradish peroxidase-labeled anti-chicken IgG and other reagents. The reaction mechanism is the coated antigen binding with IBDV-VP2-Ab in sample, and then with the enzyme-labeled anti-chicken IgG antibody to form a "coated antigen + IBDV-VP2-Ab + anti-chicken IgG HRP antibody" complex, add substrate, it will have coloration by the enzyme catalytic reaction. Color depth is proportional to the amount of IBDV-VP2-Ab, when the sample chromogenic reaction, the results detected by the microplate reader exceeds a set threshold value result judged as positive, indicating that the immune produced antibodies or natural infection exists.

5) 96 wells microplate reader

6) Distilled water or deionied water

7) Bottle or microplate washing machine

4. Sample preparation

Take animal whole blood, make serum according to regular methods, the serum should be clear, have no hemolysis.

5. Results

Set zero for the blank well, and test the A450nm (630 nm as a reference) value on the microplate-reader.

For the test to be valid:

OD value of Negative control (N) >1.0;

OD value of Positive control (P)<0.7.

If the test is invalid, the operation is in doubt, retest and observe all the reagents carefully.

Calculation method:

OD value of samples/ Average OD value of Negative control = S/N value

Result judge:

S/N ≥ 0.7, Negative;

S/N0.7, Positive.

Specifications: 96*2 wells/kit.

Expiry date: 12 months.

Storage: Storing at 2-8℃, in the dark.
