Our Products

The SA coated magnetic beads provided by Alfa Chemistry exhibit highly specific interactions with biotinylated molecules such as proteins, antibodies, and nucleic acids. This avoids the need for activation, coupling, blocking and other steps. Our products feature a high SA loading capacity and excellent hydrophilicity. Additionally, they possess superparamagnetism, rapid magnetic responsiveness, excellent redispersion stability, and magnetic stability. These characteristics make them widely applicable in the field of biology.

You Need to Know

Before using magnetic beads, they should be thoroughly mixed to prevent changes in bead concentration during the usage and to avoid prolonged ultrasound damage to the surface of the magnetic beads.
Before using the magnetic beads, magnetic separation should be carried out and washed 2-3 times with pure water or buffer solution.
Our products need to be used with magnetic separation equipment.
Our products are for research use only.
