To determine if antigens and antibodies exist in a specific sample you need a biochemistry procedure referred to as Enzyme linked immunosorbent assay. The procedure has been in use for many years in the field of pathology and medicine. ELISA test kits are used for allergies, diabetes, steroids, cancer, parasitology, thyroid, fertility, autoimmune diseases and infectious diseases.
Before purchasing ELISA kits you need to ensure they meet some requirements. You need to get the right assay format. It is essential to have the correct container system as well as the best format for your experiment. There are quite a number of formats that you can choose to work with on your project.
One of the most common formats is referred to as sandwich assay. It is named so because there are two different antibodies that sandwich the antigen. This format is popular because it is robust and sensitive. There are many times when this format is not appropriate especially if the antigen is small. It is difficult to attach antibodies which are bulky to a small antigen.
The type of antibodies you are working with are also put into consideration. In ELISAs you can use both monoclonal and polyclonal antibodies. There are cases that call for a combination of both. When choosing antibodies there are several factors to look at. For capture it is advisable to use the polyclonal antibodies and the monoclonal antibodies for the detection process. If you follow this tip you should be able to capture all the antigens and then use monoclonal antibodies to identify some specific antigens.
You have to verify that the detection and capture antibodies are a match. The two ought not to vie for the same site on the antigen. Rather they ought to perceive different antigen epitopes. The results will have errors in the event that you do not guarantee zero interference. There are methods for guaranteeing this does not occur. The most suggested path is to purchase pairs that are matched from the supplier. You can utilize the web to discover good suppliers.
Another factor to consider is interference and cross reactivity. If antibodies on the animal are compatible this could cause cross reactivity. It is easy to get antibodies for the animal that you are working with. You should always note if the cross reactivity might cause any issues. When you are working with the sandwich format it is important to match the primary detection antibodies with the secondary ones that are used for detection.
You should find out the washing as well as the blocking buffers. At times you might find a compound that will affect interaction of antigens and antibodies. You should consider detection as well. Binding can be detected using several methods. Find a kit that has the kind of detection you would like.
On the off chance that you need to figure out more about the features you can ask for details from delegates from the organizations that offer the units. They will be happy to advise you all the more about them and how to utilize them. The web is likewise a wellspring of details.
