Amine Mono Mag (4.5 µm) 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. Attribute to their uniform size, narrow size distribution, short magnetic separation time, and unique surface coating, Amine Mono Mag (4.5 µm) exhibit rapid binding chemistry and low non-specific binding of protein or nucleic acids.
