Enzyme linked immunosorbent assay is a procedure in biochemistry that is utilized to determine whether there are antibodies or antigens in a sample. For several years this procedure has been used as a tool for diagnosis in medicine and pathology. There are ELISA test kits that are meant to use for fertility, cancer, steroid, allergies, parasitology, diabetes, thyroid as well infectious and autoimmune diseases.
There are features that you should look for when buying ELISA kits. The first thing is the assay format. You need to ensure that you get the right format for your experiment. It is also important to ensure that you get the right container system. Normally ELISAs are done in 384 or 96 well plates but there are several other formats.
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 next feature you need to consider is the types of antibodies. You can utilize polyclonal antibodies as well as monoclonal antibodies in ELISAs. At times it is advisable to use a combination of both. There are several factors you need to consider when choosing antibodies. When you using a sandwich assay then you might want to try the polyclonal antibody for the capture process and the monoclonal ones for detection. By doing this you will able to capture all antigens and then utilize the antibodies that are monoclonal to detect specific antigens.
It is important to confirm that the detection and capture antibodies are making a good team. When using a sandwich assay it is important to ensure that the detection and capture antibodies are not competing for one binding site. They should be able to recognize various epitopes which are not overlapping. If there is any interferences then the results will be skewed. A sure way of avoiding this problem is buying an already matched pair. You will find many antibody suppliers who can help you out.
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.
If you want to know more about these features you can request details from representatives from the companies that sell the kits. They will be glad to inform you more about them and how to use them. The internet is also a source of information.
