Title:
SUPPORT PARTICLES FOR CHROMATOGRAPHY BASED ON MICROCAPSULES, METHOD FOR THEIR PRODUCTION AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO2003078048
Kind Code:
A3
Abstract:
The invention relates to support particles for chromatography, based on microcapsules with a porous wall, to a method for their production and to the use thereof. The inventive support particles consist of, or contain microcapsules with a pressure-resistant wall that is at the same time highly permeable to macromolecules. The inventive support material can in particular consist of purified exines of conifer pollen. Said support material is particularly suitable for chromatographic applications, which depend on a rapid exchange of polymer molecules of the size of proteins and of polymer molecules up to a specific particle size, which can reach two hundred nm, with the stationary liquid phase. Important applications are the isolation of genomic DNA from a crude extract, or the isolation of a particularly high molecular fraction of smaller molecules of a polydisperse polymer blend.
