Streptavidin-coupled Dynabeads® is the gold standard for isolation and handling of biotinylated nucleic acids, antibodies or other biotinylated ligands and targets. The very high binding affinity of the streptavidin-biotin interaction (Kd=10 -15 ) is utilized in a vast number of applications. These uniform and superparamagnetic beads are 1 µm in diameter, with a monolayer - not a multilayer - of recombinant streptavidin covalently coupled to the surface and further blocked with BSA. The monolayer of streptavidin leaves the vast majority of the biotin binding sites sterically available for bind...

Exosome - Streptavidin for Isolation/Detection, when combined with your choice of biotinylated primary antibody, enables the purification of exosomes (also called extracellular vesicles and multi-vesicular bodies) from pre-enriched samples. These exosomes can then be detected using techniques such as flow cytometry, electron microscopy, or Western blotting. The exosomes must be pre-enriched before isolation. This can be done by ultracentrifugation, or by using the fast and efficient Total Exosome Isolation (from cell culture media) reagent. • Maximum flexibility with your choice of biotinylate...

Glutathione agarose prepared by linking the sulfur atom of glutathione to crosslinked beaded agarose can be used for purification of GST fusion proteins. Each milliliter of gel can bind approximately 5-6 mg of boivine-liver GST. Adding excess free glutathione liberates the GST fragment from the matrix which can then be regenerated by washing with a high-salt buffer.
