HA0150 - Amine Mag Beads - Functionalized Magnetic Beads - Magnetic Beads (50nm-4.5μm) - By Products Type
Contact: 858-689-8808



These are hydrophilic Hi-Sur Mag (150 nm) with amine groups. These surface groups allow covalent amide bond formation to proteins/peptides via primary amine or thiol groups. The beads exhibit rapid binding chemistry and low non-specific binding of nucleic acids. Amine or thiol modified oligonucleotides, antibodies or other ligands can easily be coupled to the beads. Activation through BS3 or Sulfo-SMCC is required. The 150 nm Hi-Sur Mag Amine Beads have a large surface area, high capacity, efficient magnetic pull and a slow sedimentation rate during incubation. They have better colloidal stability than 150 nm Super Mag Beads


  • Immediate and gentle coupling at low temperature and neutral pH
  • High binding capacity
  • Fast magnetic separation
  • Significant low non-specific binding to proteins and nucleic acid


Ideal for isolation of small components such as proteins and peptides. Immobilization of primary amine or thiol groups modified labile proteins/peptides and nucleic acids. Low non-specific binding of proteins and nucleic acids.

1. Can the magnetic beads be sterilized?
Yes, carboxylic acid or amine functionalized and silica coated magnetic beads can be sterilized by washing with 70% ethanol. Protein conjugated beads cannot be sterilized.

2. Can the magnetic beads be sonicated?
Yes, short time sonication (couple seconds up to 5 minutes) is a good way to reduce aggregation of the beads and create homogenous conditions for coating or coupling. However, we don’t recommend to sonicate our magnetic beads over 10 min especially for protein conjugated beads. 

3. Are magnetic beads compatible with organic solvent?
Our magnetic beads are compatible for most polar solvent such as ethanol, methanol, acetone, isopropanol, dimethyl sulfoxide (DMSO), dimethylformamide (DMF), and acetonitrile.

4. Are magnetic beads compatible with urea?
Yes, they are compatible with 6–8 M urea.

5. Are magnetic beads compatible with EDTA?
Yes, our magnetic beads are compatible with EDTA.
