Whenever you want to purify any particular large biomolecule (e.g., IgM, virus, virus-like particle, etc.), the best way to start is by screening your working conditions. Having the biochemical properties of your molecule in mind, you should try out different mobile phases and also various column chemistries. Our CIMmultus Purification Screening Kit is intended to help scientists quickly discover the optimal stationary phase chemistry for their particular application. The CIMmultus Purification Screening Kit includes 2 different 1mL CIMmultus ion-exchange columns (QA and SO3) and one hydrophobic interaction chemistry column (OH) at a special promotional price. Using one of the selected chemistries and applying proper working conditions, you will most likely discover the right combination that will result in appropriate purity and excellent recovery of your particular molecule.
