Experimental principle of human interleukin 2 (IL-2) ELISA kit

English name: Human Interleukin 2, IL-2 ELISA

1. The level of human interleukin 2 (IL-2) ELISA Kit in the specimens was determined by double antibody sandwich method.

2. First coat the microplate with purified human interleukin 2 (IL-2) ELISAKit antibody to make a solid phase antibody.

3. Then add interleukin 2 (IL-2) ELISA Kit to the microwells coated with mAb, and then combine with HRP-labeled interleukin 2 (IL-2) ELISA Kit antibody to form an antibody-antigen-enzyme-labeled antibody complex After thorough washing, add substrate TMB to develop color. TMB is converted into blue under the catalysis of HRP enzyme, and into the final yellow under the action of acid.

4. The color depth is positively correlated with the interleukin 2 (IL-2) ELISA Kit in the sample.

5. Finally, the absorbance (OD value) is measured with a microplate reader at a wavelength of 450 nm, and the concentration of human interleukin 2 (IL-2) ELISA Kit in the sample is calculated from the standard curve

Objective: To determine the content of interleukin 2 (IL-2) ELISA Kit in human serum, plasma and related liquid samples.

6. Serum: Blood coagulates naturally at room temperature for 10-20 minutes, centrifuged for about 20 minutes (2000-3000 rpm). Collect the supernatant carefully and centrifuge again if a precipitate appears during storage. Avoid any cell stimulation during the operation. Use test tubes free of pyrogens and endotoxins.

7. Plasma: EDTA or sodium citrate should be selected as the anticoagulant according to the requirements of the specimen. After mixing for 10-20 minutes, centrifuge for about 20 minutes (2000-3000 rpm) to remove particles. Collect the supernatant carefully, and centrifuge again if there is any precipitate.

safety:
1. Avoid direct contact with stop solution and substrate. If you accidentally come into contact with these liquids, please rinse them with water as soon as possible.
2. Do not eat, drink, smoke or use cosmetics during the experiment.
3. Do not touch any ingredients in the kit with your mouth.

4 Keep Elisa kit away from children
