Service manual of PPA-ELISA Kit for Classical Swine Fever Virus IgG antibody

Products IntroductionClassical Swine Fever (CSF) is a high morbidity, high mortality and high contagious viral disease, which caused huge losses to the domestic pig industry.In the prevention of swine fever immunity in vaccinated swine fever vaccine, due to a variety of factors could cause the pig does not produce or produce low levels of classical swine fever virus antibodies.E2 structural protein is involved in the process of viral infection of cells and is the major protective antigen protein of CSFV,that can induce protective antibodies. This kit by enzyme-linked immunosorbent assay detection of porcine serum antibodies against CSFV E2 protein IgG, classical swine fever vaccine for the immunization levels of antibody to monitor the dynamic and guide the work of immunization to assess immune status of pig farms swine fever, swine can also be used Epidemiological investigation of plague.

Operation Steps

1. The equipment need to be prepared

1.1 Pipette 10μl100μl200μl1000μl range.

1.2 Tips500ml graduated cylinder1.5ml EPmicroplate reader.

1.3 Distilled or deionized water.

2. Sample preparation

Dilution of samples to be tested serum samples were diluted 100 times (2μl of serum samples diluted by adding 198μl sample diluent solution), the sample need tofully mix before joining antigen-coated plates, dilution of the sample to be seized attention in different replacement tips.

Note: Preparation of blood serum samples should not be used for hemolytic phenomenon; can not dilute the negative and positive control serum, long time do not set the positive and negative serum and IgG put in -20 preservation.

3. Steps(* kit need to restore to room temperature and reagents need to shock mix before using.)

3.1A1and A2 well were added to 100μl negative control serum

3.2 A3and A4 well were added to 100μl positive control serum

3.3Other wells were added to 100μl the diluted sample(1:100 dilution) and make a record

3.4 ELISA plates were Incubated 1 hour under room temperature or 37 conditions

3.5Removed the reaction solution in microplate, and add 300μl wash solution per well to wash. Washing time should be controlled in 2-3 minutes,andWashing times should be controlled in 3-5 times.(*20×concentrated washing solution has diluted with distilled water or deionized water before use. If crystals, you must first dissolve before they are allowed dilution).

3.6 Added 100μl diluted enzyme conjugates (SPA-HRP) per well

3.7 ELISA plates were Incubated 1 hour under room temperature or 37 conditions

3.8 Repeat steps 3.5

3.9 Added 100μl per well of substrate solution

3.10 ELISA plates were Incubated in room temperature and  dark conditions

3.11 At last, end the reaction by adding stop solution.

3.12 Test the OD value in each reaction well with ELISa at 450nm wavelength.

4. Result determination

4.1 Negative control: Under normal circumstances, the OD450 value of the negative control well ≤ 0.2.

4.2 Positive control: Under normal circumstances, the OD450 value of the positive control well≥0.4.

4.3 Critical value (CO) calculation:critical value =0.19 + negative control mean.If more than 0.20,the negative control OD450 value should be discarded.If all the negative control OD450 values are greater than 0.20,the experiment need to be repeated. Negative control well below the 0.05 to 0.05 calculated.

4.4 Results found: test specimens OD450 value ≥critical value to determine the sample was positive; test specimens OD450 value <critical value to determine the test sample was negative

Attention      

(1) Substrate solution and stop solution are irritating to the skin, pay attention to protection.

(2)Substrate solution not exposed to strong light and any oxidant.

(3) All reagents should be stored at 2 ~ 8 . Return to room temperature before use, after use back into the 2 ~ 8 .

(4) Attention to prevent contamination of kit components

(5)Do not use expired reagents, the composition of different batches of kits do not mix.

Specification96 wellx 2 /kit

Storage and Expiry date: store 2-8, not frozen, 6 months
