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.
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.
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 sort of antibodies you working with are likewise put into attention. In ELISAs you can utilize both polyclonal and monoclonal antibodies. There are cases that call for a consolidation of both. At the point when picking antibodies there are a few variables to place into consideration. For detection it is fitting to use monoclonal antibodies. Polyclonal antibodies can be used for capturing. In the event that you take after this tip you ought to have the capacity to catch all antigens and afterward utilize monoclonal antibodies to distinguish some particular 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.
An alternate component to consider is cross reactivity. In the event that antibodies on the creature are good this could result in cross reactivity. It is not difficult to get antibodies for the creature that you are concerned with. You ought to dependably note if the cross reactivity is a problem. If you choose the sandwich format it is vital to match the essential location antibodies with the auxiliary ones that are utilized for identification.
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.
