What is ELISA?
ELISA, short for enzyme-linked immunosorbent assay, is a method to detect the presence of a ligand, which usually is a protein, in a liquid sample using antibodies directed against the protein to be measured.
Compared with other immunoassay methods, ELISA is featured with higher sensitivity, specificity and throughput. Moreover, it is easy to perform. These advantages make ELISA be a very popular choice for researchers from various areas.
How does an ELISA Kit Work? What is the Typical ELISA Workflow?
Firstly, the antigens of interest are immobilized on the microplate by overnight incubation. This step forms antigen-coated wells.
Secondly, add the enzyme-labeled antibodies to the wells. Sometimes the unconjugated antibodies are added before the addition of the enzyme-labeled antibodies according to the experiment requirement. The antigens are directly captured by the enzyme-labeled primary antibodies or indirectly captured via the enzyme-labeled secondary antibodies that have been attached to the unconjugated antibodies on the microplate.
Thirdly, specific biotinylated detection antibodies are added to the wells to enable detection of the captured antibodies. The addition of the substrate solution is then added to each well. The color reaction is presented after incubation of the plated at 37 degrees celsius for 5 minutes.

Select Right ELISA kits for Your Experiments
Once mentioned ELISA, the first problem is how to choose a right ELISA kit for experiments. Before that, you must distinguish the four common types of ELISA, including direct ELISA, indirect ELISA, sandwich ELISA and competitive ELISA, and figure out the advantages and disadvantages of each ELISA.
Start your ELISA Experiment
After choosing your right ELISA kit, a guide on how to do the pre-experiment before ELISA experiment must be required. And we have prepared it for you. Besides a general ELISA Protocol is also ready.
In addition, the CUSABIO's technicians have summarized the process of how to do ELISA data analysis after accomplished the experiment. We believe it is very helpful.
If you get into trouble in the process, don't forget to check the common problems of ELISA experiment and ELISA FAQs. You may find answers to the problems.
