We offer a variety of resins for the purification of biotinylated or desthiobiotinylated proteins, peptides, and other molecules. These resins are available in multiple pack sizes, as well as in spin columns, kits, and coated plates for some ligands. Select products based on avidin, streptavidin, NeutrAvidin™, or CaptAvidin™ proteins.
- Product choice—a variety of biotin binding choices to meet your purification needs
- High performance—resins that maximize binding capacity and elution conditions
- Flexible—available in multiple pack sizes
