High Resolution U/HPLC Separation of Monoclonal Antibodies on BIOshell™ IgG 1000 Å C18

High resolution separtion of monoclonal antibodies (mAbs), mAb variants, and other, high molecular weight, hydrophobic proteins.

The BIOshell™ IgG 1000 Å C18 column, based on Fused-Core® particles, is non-polar in nature.  Utilizing a combination of water and methanol or acetonitrile with an ion pairing reagent (like trifluoroacetic acid (TFA) or difluoroacetic acid (DFA), most separations of mAbs and their variants can be achieved. For most mAb workflows, elevated column temperatures (60 °C or higher), is usually required. The BIOshell™ IgG 1000 Å C18 column is suitable for most proteins with molecular weights up to 500 kDa; this is due to the 1000 Å pore within the particle.

BIOshell™ IgG 1000 Å C18 is a high-speed, high-performance liquid chromatography column based on a superficially porous Fused-Core® particle design. The Fused-Core® particle provides a thin porous shell of high-purity silica surrounding a solid silica core.  This particle design exhibits very high column efficiency due to the shallow diffusion paths.
