MC1000 - Carboxyl Mag Beads - Functionalized Magnetic Beads - Magnetic Beads (50nm-4.5μm) - By Products Type
Contact: 858-689-8808



Carboxyl Mono Mag (1 µm, MC) are hydrophilic magnetic beads with carboxylic acid groups. These surface groups allow covalent amide bond formation to proteins/peptides via primary amine (NH2) groups. Oligonucleotides, antibodies or other ligands with amine groups can be easily coupled to the beads. Activation through carbodimide is required. With their large surface area, uniform size, narrow size distribution and unique surface coating, Carboxyl Mono Mag (1 µm, MC) exhibit high binding capacity and low non-specific binding of protein or nucleic acids. Their compact structure also ensures faster magnetic separation than Hi-Sur Mag Beads (1 µm).


  • Significantly low non-specific binding to proteins and nucleic acid
  • High binding capacity
  • Immediate and gentle coupling at room temperature and neutral to low pH
  • Narrow size distribution, CV≤5%; No iron exposure to ensure lowest autosignal, particularly with respect to chemiluminescence
  • Comparable performance with Dynabeads Myone Carboxylic Acid.

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.
