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 buying ELISA units you have to guarantee they meet a few prerequisites. You have to get the right test arrangement. It is crucial to have the right compartments and additionally the design for your analysis should be good. There are many formats to choose from when you are getting started on your project.
The sandwich assay is mainstream with numerous individuals preferring it. The main reason behind why it is alluded to as a sandwich is on account of there being an antigen which is between a pair of antibodies. This arrangement is favored in view of its robustness and sensitivity. In a few cases this configuration is not favored. On the off chance that you have a little antigen then you will think that it hard to append substantial antibodies on it.
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.
All these features can be explained in details. If you have any questions you should address them to the company representatives. They have a lot of knowledge about the kits and which situations they are best used in. You can also read the technical specifications online.
