Experimental principle of human tumor necrosis factor-related activation-inducing factor (TRANCE) ELISA kit

1. The level of human tumor necrosis factor-related activation-inducing factor (TRANCE) ELISA Kit in specimens was determined by double antibody sandwich method.

2. First, coat the microplate with purified human tumor necrosis factor-related activation-inducing factor (TRANCE) ELISA Kit antibody to prepare a solid-phase antibody.

3. Then add the tumor necrosis factor-related activation inducing factor (TRANCE) ELISA Kit to the microwells coated with mAb in turn, and then combine with the HRP-labeled tumor necrosis factor-related activation inducing factor (TRANCE) 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 tumor necrosis factor-related activation-inducing factor (TRANCE) 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 tumor necrosis factor-related activation-inducing factor (TRANCE) ELISA Kit concentration in the sample is calculated from the standard curve

Objective: To determine the content of tumor necrosis factor-related activation-inducing factor (TRANCE) ELISA Kit in human serum, plasma and related liquid samples.

5. Serum: The blood will naturally coagulate at room temperature for 10-20 minutes and centrifuge 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.

6. 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.
