Swine Influenza Virus Antibody ELISA Test Kit One Step Rapid 192 Wells/Kit

Swine Influenza Virus Antibody ELISA Test Kit 96*2 Wells/Kit ISO9001

1. Principle

Influenza virus, referred to as influenza virus, can be divided into three types: A, B, and C. Among them, influenza A virus is divided into many subtypes according to different hemagglutinin H antigen and neuraminidase N antigen. Influenza A viruses are currently known to infect a variety of animals including birds, humans,pigs, horses, dogs, whales etc.
This kit use blocking ELISA method, to detect influenza A virus antibody in serum of multiple animal like Swine, birds, dog, horse etc. When testing, add diluted serum sample, after incubation, if there is influenza A 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-Influenza A 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 wavelength to measure the absorbance A value in reaction wells after adding stop solution to stop the reaction.

2. Reagents and contents

3. Material required not provided

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) Antigen 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) Antigen 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, 60ul/well, then add serum sample to the reaction wells, 40ul/well, blow and mix evenly(Do not mix use tips)
3) Cover it with Adhesive Foil, incubate at37℃ for60minutes;
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,incubateat37℃ 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,incubateat37℃ in darkfor10 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 > 0.4 ;
Calculate method:
Sample OD value/Average OD value of Negative control=S/N value
Results interpretation
S/N value ≥ 0.4: Negative;
S/N value＜ 0.4: Positive.

9. Storage and expire date

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

Introduction to Swine Influenza Virus

Swine influenza virus (Swine Influenza Virus) is an orthomyxovirus that can cause endemic influenza in pigs. On April 30, 2009, the World Health Organization renamed the new deadly virus previously known as swine flu H1N1 influenza A. Swine influenza is a highly infectious respiratory infectious disease of pigs. It is characterized by rapid onset, sudden fever and other cold symptoms. The recovery is as fast as the occurrence. Swine influenza is caused by a influenza virus, which belongs to the same genus as the influenza virus infecting human beings. The disease virus has the characteristics of co infection of humans and animals. The occurrence of pig influenza in pig herds is usually related to the introduction of new pig herds in pig farms.
