Experimental principle of human vascular endothelial cell growth factor receptor 3 ELISA kit

2024-05-17 05:06:53

1. The level of human vascular endothelial cell growth factor receptor 3 ELISA Kit in the specimen was determined by double antibody sandwich method.

2. First coat the microplate with purified human vascular endothelial cell growth factor receptor 3 ELISA Kit antibody to make a solid phase antibody.

3. Then add the vascular endothelial cell growth factor receptor 3 ELISA Kit to the monoclonal antibody-coated microwells in sequence, and then combine with HRP labeled vascular endothelial cell growth factor receptor 3 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 vascular endothelial growth factor receptor 3 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 vascular endothelial cell growth factor receptor 3 ELISA Kit in the sample is calculated from the standard curve

Objective: To determine the content of vascular endothelial growth factor receptor 3 ELISA Kit in human serum, plasma and related fluid 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

Zipper Luggage

This is a promotion business travel suitcase for men, which is suitable for travelling. It is use the zipper to close the luggage. The surface material of the ABS Luggage is abs plate, not easy to peel and break. The wheel of the suitcase bag is 360 degrees universal double wheels design for rolling smoothly. The Tie rod still uses the solid aluminum alloy tie Rod. Four corners of the surface all have been designed the plastic wrap angle to avoid the damage by violence. About inside space of the business suitcase, it is big enough to help store more things.
