Amine Super Mag (100 nm) are hydrophilic magnetic beads with amine groups. These surface groups allow covalent bond formation to proteins/peptides via primary amine, carboxy or thiol groups. Oligonucleotides, antibodies or other ligands with these groups can be easily coupled to the beads. Activation through EDC or Sulfo-SMCC is required. With large surface area, excellent colloidal stability and unique surface coating, the Amine Super Mag (100 nm) exhibit high binding capacity and low non-specific binding of protein or nucleic acids.
