  • Benzimidazole Compounds And Their Use As Chromatographic Ligands
    Publication number: 20150360147
    Abstract: The present invention provides a new method for isolation and/or purification of immunoglobulins from a solution containing one or more immunoglobulins using a solid phase matrix represented by the formula: M-SP-L, wherein M is designates a matrix backbone, SP designates a spacer and L designates a substituted benzimidazole ligand.
    Type: Application

  • Asymmetric porous adsorptive bead
    Patent number: 9067976
    Abstract: The present invention relates to an asymmetric chromatography media suitable for separations applications, particularly as packed bed, fluidized bed or magnetized bed chromatography media. In certain embodiments, the asymmetric chromatography media comprises asymmetric particles, preferably beads, having at least two distinct, controlled pore size distributions. Preferably one of the distinct pore size distributions is in an internal region of the particle, and the other is in an external region or coating on the particle. These distinct pore size distributions can be modified with uniform or alternatively unique functional groups or mixtures of functional groups. The present invention allows for the control over pore size distribution within an asymmetric porous particle by providing a distinct internal region, preferably in the form of a bead, and a distinct external region, preferably in the form of a coating on the bead.
