- Easy to run
- Rapid protocol
- Convenient precoated, removable 8-well strips
The total assay incubation time is only 4 hours. A monoclonal capture antibody specific for Human TNF-α has been coated onto the wells of the 96-well plate provided. Samples, including a standard of known Human TNF-α content, controls, and unknowns, are pipetted into these wells. During the first incubation, Human TNF-α antigen binds to the immobilized capture antibody on one site. After washing, a biotinylated monoclonal antibody specific for Human TNF-α is added. During the second incubation, this antibody binds to the immobilized Human TNF-α antigen at a different site. After washing, a streptavidin-horseradish peroxidase (HRP) is added. This binds to the biotinylated detection antibody to complete the four–member sandwich. After a second incubation and washing to remove all unbound enzyme, a substrate solution (TMB) is added, which is acted upon by the bound enzyme to produce color. The intensity of this colored product is directly proportional to the concentration of Human TNF-α present in the original specimen and the optical density can be read on a standard microplate reader.

The kit comes with a capture antibody precoated to the plate, eliminating an overnight coating process. The plates are machine coated to provide low variability well-to-well. Furthermore, the plate comes as removable 8-well strips allowing you to run as few samples as you want.
Each ELISA kit is validated for sensitivity, specificity, precision, and lot-to-lot consistency. See protocol insert for more information on validation.
