|Streptavidin Coated Microspheres, 0.2μm
When circumstances call for the rapid development of microsphere reagents, particles coated with affinity binding proteins offer a ready solution. Affinity binding protocols are straightforward, typically involving a simple incubation of the spheres with the appropriate ligand. Binding proteins also provide an opportunity to optimally orient the ligand, as with the end-point immobilization of biotinylated oligonucleotides to streptavidin-coated microspheres, or the Fc-specific immobilization of antibodies via Protein A or G. Particles coated with binding proteins also find significant use in purifications. Streptavidin-coated microspheres are often used in the isolation of biotinylated PCR amplicons. Protein A and Protein G microspheres are utilized for purification of antibodies and Fc-tagged fusion proteins, as well as for the recovery of Ab/Ag complexes in immunoprecipitation. Bangs streptavidin and SuperAvidin™ coated microspheres offer simple and extremely stable binding of biotinylated molecules, such as antibodies, peptides, and oligonucleotides for use in diagnostics, screening, and affinity purifications.. Streptavidin coated microspheres are available as ~1% solids (w/v) aqueous suspensions in four standard volumes: 1mL, 2mL, 5mL, or 10mL.: |
