The remarkably strong interaction between the small molecule biotin and the proteins streptavidin or (neutr)avidin is widely exploited in biological research 1. Biotin-binding proteins have been ...

Streptavidin and avidin are used ubiquitously because of the remarkable affinity of their biotin binding, but they are tetramers, which disrupts many of their applications. Making either protein ...

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 ...

A novel streptavidin variant with improved biotin binding characteristics allows stable monovalent detection of biotinylated targets for imaging applications and can be recombinantly fused to ...

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 ...

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 ...

Quantum Dot Corporation (QDC) has announced a new addition to its nanocrystal-based family of fluorescent labels: the Qdot 705 streptavidin conjugate for ultra-bright, near infra-red bio-detection.

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 ...
