Conclusion

Using Mix&Go, it is possible to produce fully functional magnetic particles ready for Protein A binding with far higher binding capacity at approximately 100 times lower cost than with existing magnetic particles.  In addition, Protein A coupling is a simple one-step procedure.  Use of Mix&Go’s aqueous base chemistry greatly simplifies large scale manufacturing with tight batch reproducibility. While Protein A and many other factors contribute to bioprocessing costs, we believe it is possible to decrease magnetic bioprocessing costs to match or even undercut costs of current column chromatography methods.
