Affinity ligand magnetic microspheres have uniform particle size, stable and controllable surface functional groups, and excellent experimental repeatability. They can be used for high-throughput purification, and can directly obtain high-purity target protein from coarse samples. In addition, VDO Biotech provide customized microspheres with different particle sizes and surface functional groups to meet the special purification requirements of different samples and applications.

Advantages of magnetic microspheres method:

1) No need for time-consuming and laborious centrifugation and filtration steps for crude protein

2) No need for column packing and column chromatography, and no need for expensive column chromatography equipment

3) High yield and high purity target protein can be easily obtained within one hour

4) Parallel processing of multiple samples significantly improves work efficiency and greatly reduces equipment, time and labor costs.
