Avidin is a protein derived from both avians and amphibians that shows considerable affinity for biotin, a co-factor that plays a role in multiple eukaryotic biological processes. Bethesda, MD 20894, Web Policies Amplification methods for the immunolocalization of rare molecules in cells and tissues. This method may be chosen when a biotinylated treatment molecule is attached to a carrier molecule.9, Although there are complex variations involved in each separate diagnostic test, the basic mechanism involves attaching biotin to the molecule used as a probe to detect whatever is being looked for in the body (a process called biotinylation), applying this biotinylated probe to the tissue being tested, and then detecting the bound biotinylated probe molecules-substance with labeled avidin molecules. Biotin, also known as B-vitamin B7 (formerly vitamin H and coenzyme R) is water soluble. M. Plank, G. H. Wadhams, and M. C.
