Content of human kallikrein 11 (KLK 11)
Experimental principle of human kallikrein 11 (KLK 11) ELISA kit
English name: Human Kallikrein 11, KLK 11 ELISA
1. The level of human kallikrein 11 (KLK 11) ELISAKit in the specimen was determined by the double antibody sandwich method.
2. First coat the microplate with purified human kallikrein 11 (KLK 11) ELISAKit antibody to make a solid phase antibody.
3. Then add kallikrein 11 (KLK 11) ELISAKit to the microwells coated with mAb in turn, and then combine with HRP-labeled kallikrein 11 (KLK 11) ELISAKit antibody to form antibody-antigen-enzyme labeled antibody After thorough washing, the complex is added with substrate TMB for color development. TMB is converted into blue under the catalysis of HRP enzyme, and into the final yellow under the action of acid.
4. The shade of the color is positively correlated with KL Kit 11 (KLK 11) ELISAKit 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 kallikrein 11 (KLK 11) ELISAKit in the sample is calculated by a standard curve
.
OBJECTIVE: To determine the content of kallikrein 11 (KLK 11) ELISAKit 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
