1. Coated buffer (1X)
Dilute PBS (10X) at 1:10 in deionized water.
2. Capture antibody
Antibodies (250X) were captured in the coated buffer (1X) with 1:250 dilution.
3. 5X ELISA/ELISPOT dilution
Dilute a concentrate (5X) of 1:5 in deionized water.
4. Standard
The protein standard was reconstructed by adding distillate water. The redissolved volume is indicated on the label of the standard bottle. Let the standard redissolve for 10-30 minutes. Swirl or mix gently to ensure complete uniform dissolution.
5. Detect antibody
Detection of antibodies in 1:250 diluted ELISA/ELISPOT solution (250X).
6. Enzyme
Dilute HRP concentrate with 1:100 in ELISA/ELISPOT diluted solution (100X).

1. ELISA plate with captured antibody in coated buffer. Sealed plate and incubated overnight at 4°C.
2. Drain the hole and wash it 3-5 times with washing buffer. Leaving time for soaking during each washing step can improve washing results. Imprinted plate on blotting paper to remove any residual buffer.
3. The well was sealed with ELISA/ELISPOT Diluent (1X). Incubate at room temperature for 1-2 hours.
4. Prepare standards (see Test Protocols).
5. Drain with washing buffer and wash at least once.
6. Double the series dilution of the top standard products to make standard curves with 8 points in total. To do this, ELISA/ELISPOT Diluent (1X) was added to the Wells, leaving the remaining holes empty. The highest standard concentration is added to the remaining empty Wells. Transfer the top standard from hole A to hole B. Mix the contents of both B Wells by repeated suction and injection, then transfer 1to two wells C. Be careful not to scratch the surface of the micropores. Continue this process 4-6 times.
7. Add the sample to the appropriate well.
8. Add ELISA/ELISPOT Diluent (1X) into the blank well.
9. Seal the plate and incubate at room temperature for 2-3 hours.
10. Prepare for antibody test (see Test Protocol).
11. Drain and rinse as in Step 2. Repeat the cleaning for a total of 3-5 times. Allow time for soaking in each wash step to improve washing effect. Imprinted plate on blotting paper to remove any residual buffer.
12. Add diluted test antibody to all Wells.
13. Seal the plate and incubate at room temperature for 1-2 hours.
14. Prepare streptavidin-HRP (see Test Protocol).
15. Drain and rinse as in Step 2. Repeat the cleaning for a total of 3-5 times. Setting aside a soaking time (about 1-2 minute) in each washing step can improve the washing effect. Imprinted plate on blotting paper to remove any residual buffer.
16. Add diluted Streptavidin-HRP.
17. Seal the plate and incubate at room temperature for 30-45 minutes.
18. Drain and wash as described in step 2, making sure to allow 1-2 minutes of soaking time before draining. Repeat a total of 6-8 washes.
19. Add 1X TMB solution.
20. Incubate at room temperature for 15-30 minutes.
21. Add the stop solution.

Plates were read at 450 nm. If there is wavelength subtraction, subtract 570nm from the 450nm value and analyze the data.

Interleukin-4 (IL-4) is a pleiotropic, immune-modulatory cytokine produced by activated T cells, and serves as a ligand for interleukin 4 receptor. IL-4 has been found to have the broadest range of actions. The interleukin 4 receptor also binds to IL13, which may contribute to many overlapping functions of this cytokine and IL13. STAT6, a signal transducer and activator of transcription, has been shown to play an important role in mediating the immune regulatory signal of IL-4. The IL-4 gene, IL-3, IL-5, IL-13, and CSF2 form a cytokine gene cluster on chromosome 5q. In particular, IL-4 is located in close proximity to IL13 on the chromosome. Further, the IL-4 gene, IL13 and IL5 are found to be coordinated by several long-range regulatory elements over a 120 kilobase range on the chromosome. IL-4 delta 2 is a known splice variant of IL-4.
