The purpose of an ELISA is to determine if a particular protein is present in a sample and if so, how much. There are two main variations on this method: you can determine how much antibody is in a sample, or you can determine how much protein is bound by an antibody. The distinction is whether you are trying to quantify an antibody or some other protein. In this example, we will use an ELISA to determine how much of a particular antibody is present in an individuals blood.
ELISAs are performed in 96-well plates which permits high throughput results. The bottom of each well is coated with a protein to which will bind the antibody you want to measure. Whole blood is allowed to clot and the cells are centrifuged out to obtain the clear serum with antibodies (called primary antibodies). The serum is incubated in a well, and each well contains a different serum (see figure below). A positive control serum and a negative control serum would be included among the 96 samples being tested.

Colon polyp facts Colon polyps are growths on the inner lining of the colon and are very common. Colon polyps are important because they may be, or may become malignant (cancerous). They also are important because based on their size, number, and microscopic anatomy (histology); they can predict which patients are more likely to develop more polyps and colon cancer. Changes in the genetic material of cells lining the colon are the cause of polyps. There are different types of colon polyps with differing tendencies to become malignant and abilities to predict the development of more polyps and cancer. It is important to recognize families with members who have familial genetic conditions causing polyps because some of these conditions are associated with a very high incidence of colon cancer, and the cancer can be prevented or discovered early.
