The use of avidin-biotin interaction in immunoenzymatic techniques provides a simple and sensitive method to localize antigens in formalin-fixed tissues. Curr Top Pathol. Because biotin is relatively small (244.3 Daltons), it can be conjugated to many proteins and other molecules without significantly altering their biological activity. In the context of immunohistochemistry and immunoblotting, biotin is most often conjugated to primary or secondary antibodies, and the biotin tag is then detected with a biotin-binding protein that is conjugated to an enzyme, fluorophore or other reporter molecule. To overcome this limitation, modified versions of Avidin resins and modified forms of biotin labeling reagents are commercially available which make the interaction readily reversible. In other procedures, the antibody is first immobilized and then used to capture the target antigen. sharing sensitive information, make sure youre on a federal Among the several staining procedures available, the ABC method, which involves an application of biotin-labeled secondary antibody followed by the addition of avidin-biotin-peroxidase complex, gives a superior result when compared to the unlabeled antibody method. While not as rapid as PCR methods, this technique is also valuable for the in situ hybridization to bacterial colonies and bacteriophage plaques when performing large cloning Screens. Typically, the avidinbiotinylated enzyme are mixed together in a specified ratio to prevent avidin saturation and incubated for about 15 minutes at room temperature to form the complex.

While many laboratories have switched to more rapid forms of detection, such as real-time polymerase chain reaction (RT-PCR), also known as quantitative PCR (qPCR), northern and Southern blotting remain effective methods for confirming the presence of specific DNA and RNA sequences as well as their size and integrity. For example, membrane-impermeable biotinylation reagents can be used to tag cell surface proteins and then facilitate separation of those proteins from all other cellular proteins. Because the biotin label is stable and small, it rarely interferes with the function of labeled molecules enabling the Avidin-biotin interaction to be used for the development of robust and highly sensitive assays. Although the Avidin-biotin system is simple to set up and use, it does have certain limitations.
