Porcine PRV-gE
FOR RESEARCH USE ONLY
Assay range：6ng/L - 160ng/L 96 determinations
Purpose
This kit allows for the determination of PRV-gE concentrations in Porcine serum cell
culture supernates and other biological fluids
Principle of the assay
The kit assay Porcine PRV-gE level in the sample use Purified Porcine PRV-gE
antibody to coat microtiter plate wells make solid-phase antibody then add PRV-gE to wells
Combined PRV-gE antibody which With HRP labeled become antibody - antigen -
enzyme-antibody complex after washing Completely Add TMB substrate solutionTMB
substrate becomes blue color At HRP enzyme-catalyzed reaction is terminated by the addition
of a sulphuric acid solution and the color change is measured spectrophotometrically at a
wavelength of 450 nm. The concentration of Porcine PRV-gE in the samples is then
determined by comparing the O.D. of the samples to the standard curve.

Specimen requirements
1. extract as soon as possible after Specimen collectionand according to the relevant
literature and should be experiment as soon as possible after the extraction. If it can’t
specimen can be kept in -20 ℃ to preserve Avoid repeated freeze-thaw cycles.
2. Can’t detect the sample which contain NaN3 because NaN3 inhibits HRP active.
Assay procedure
1. Dilute and add sample:Dilute Original density Standard as follow table:
160ng/L
5 Standard 150µl Original density Standard+150µl Standard diluent
80ng/L
4 Standard 150µl 5 Standard+150µl Standard diluent

2 Standard 150µl 3 Standard +150µl Standard diluent

1 Standard 150µl 2 Standard +150µl Standard diluent
2.add sample：Set blank wells separately (blank comparison wells don’t add sample and
HRP-Conjugate reagent other each step operation is same). testing sample well. add Sample
dilution 40µl to testing sample well then add testing sample 10µl (sample final dilution is
5-fold) add sample to wells don’t touch the well wall as far as possible and Gently mix.
3.Incubate: After closing plate with Closure plate membrane incubate for 30 min at 37℃.
4.Configurate liquid: 30-fold(or 20-fold) wash solution diluted 30-fold (or 20-fold) with distilled
water and reserve.
5.washing：Uncover Closure plate membrane discard Liquid dry by swing add washing buffer
to every well still for 30s then drain repeat 5 times dry by pat.
6.add enzyme：Add HRP-Conjugate reagent 50µl to each well except blank well.
7.incubate：Operation with 3.
8.washing：Operation with 5.
9.color：Add Chromogen Solution A 50ul and Chromogen Solution B to each well evade the
light preservation for 15 min at 37℃
10.Stop the reaction：Add Stop Solution50µl to each well Stop the reaction(the blue color
change to yellow color). 3
11.assay：take blank well as zero Read absorbance at 450nm after Adding Stop Solution and
within 15min.

calculate
Calculate
Take the standard density as the horizontal the OD value for the vertical draw the 4
standard curve on graph er Find out the corresponding density according to the sample
OD value by the Sample curve multiplied by the dilution multiple or calculate the straight line
regression equation of the standard curve with the standard density and the OD value with the
sample OD value in the equation calculate the sample density multiplied by the dilution factor
the result is the sample actual density.
Important notes
1. The kit takes out from the refrigeration environment should be balanced 15-30 minutes in
the room temperature ELISA plates coated if has not use up after opened the plate should
be stored in Sealed bag.
2. washing buffer will Crystallization separation it can be heated the water helps dissolve
when dilute . Washing does not affect the result.
3. add Sample with sampler Each step And proofread its accuracy frequently avoids the
experimental error. add sample within 5 min if the number of sample is much recommend
to use Volley .
4. if the testing material content is excessively higher (The sample OD is bigger than the first
standard well )please dilute Sample (n-fold) Please diluente and multiplied by the dilution
factor.（×n×5）.
5. Closure plate membrane only limits the disposable use to avoid cross-contamination.
6. The substrate evade the light preservation.
7. Please according to use instruction strictly The test result determination must take the
microtiter plate reader as a standard.
8. All samples washing buffer and each kind of reject should according to infective material
process.
9. Do not mix reagents with those from other lots.
