The complex is stable to 100 C, and significantly stable to detergents and denaturants.10 Avidin is stable to 85 C without biotin. Three systems--the indirect, peroxidase-antiperoxidase (PAP), and avidin-biotin peroxidase complex (ABC) detection system--were compared in quantitative ELISA titration and inhibition assays and tissue labeling with keratin antisera. As a result of carbohydrate removal, lectin binding is reduced to undetectable levels, yet the biotin-binding affinity is retained because the glycosylation is not necessary for this activity. Immunohistochemical staining intensity is a function of the enzyme activity, and improved sensitivity can be achieved by increasing the number of enzyme molecules bound to the tissue. . The word "biotin" comes from the ancient Greek word "biotos," which means "life" or "sustenance." B vitamins, and specifically biotin, help keep your skin, hair, eyes, liver, and nervous system healthy. There are four binding sites for biotin on each avidin molecule and two binding sites for avidin on each biotin molecule. The avidin-biotin system is a simple yet elegant system to link proteins in immunoassays by exploiting the very high affinity of hen egg-white avidin for biotin (vitamin B7).
