To figure out whether antibodies and antigens exist in a particular specimen you require a chemistry technique alluded to as Enzyme linked immunosorbent assay. The method has been used for a long time in the pharmaceuticals field. ELISA test kits are utilized for hypersensitivities, diabetes, steroids, tumor, parasitology, fertility, thyroid, immune system ailments and other maladies.
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.
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.
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.
Cross reactivity as well as interference is another feature to look for. Cross reactivity can be caused by antibodies that are on the host animal being compatible. It is not hard to purchase antibodies that are obtained from the animal in question. However, consider it important to find out if cross reactivity might pose a problem. In the sandwich format the secondary antibody that is utilized for the detection process must be right for the primary antibody that was utilized during detection.
It is also important to figure out what is in the blocking as well as the washing buffers. Sometimes they may contain compounds that are likely to alter interaction of the antibodies and the antigens. The final factor to consider is detection. There are several ways of detecting binding. You need to find a kit that utilizes detection that you prefer.
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.
