Applications
Streptavidin-biotin binding is known as one of the most stable noncovalent interactions and is stably maintained over wide range of temperature, pH and denaturing agent. This binding has been widely used in the field of biotechnology such as molecular labeling, immobilization and drug delivery system and has been applied for diagnostic and research test kit. Especially in immunochemical assays, it enables to develop highly sensitive detection system.
