Carboxyl Magnetic Beads


Carboxylated Magnetic Beads are nano-superparamagnetic beads coated with carboxylic acid functional groups, which can be activated (e.g. using EDC and sulfo-NHS) and then reacts with amines on nucleic acid, protein, antibodies or other molecules to form stable amide linkages. After that, the beads can be separated from the solution using magnet for downstream experiments, such as enzymatic reactions or immunopurification of other large molecules.
