Receptor–ligand interactions are essential for biological function and their binding strength is commonly explained in terms of static lock-and-key models based on molecular complementarity. However, ...

Biotin can amplify signals by forming complexes of large size with avidin or streptavidin. There are several techniques that use biotinylated secondary antibodies for this purpose, which are dealt ...

Recent research by Rafael C. Bernardi at the University of Illinois, Urbana-Champaign examines why a common tool in biotechnology -- the binding of streptavidin to biotin -- shows different mechanical ...

A team of researchers from the University at Buffalo in Amherst, NY have successfully engineered a novel variant of streptavidin that forms a stable monomer and is capable of monovalent biotin ...

Sera-Mag™ Streptavidin-Coated Magnetic Beads and SpeedBeads exhibit high affinity and sensitivity for biotinylated target molecules, along with fast reaction kinetics, increasing throughput and ...
