PARTIKELMATERIAL FÜR WIRBELBETTREINIGUNG VON BIOMAKROMOLEKÜLEN WIE PLASMID-DNS, CHROMOSOMEN- DNS, RNS,VIRALE DNS, BAKTERIEN UND VIREN
The present invention relates to particulate material having a density of at least 2.5 g/ml, where the particles of the particulate material have an average diameter of 5-75 mu m, and the particles of the particulate material are essentially constructed of a polymeric base matrix, e.g. a polysacchar...

| description | The present invention relates to particulate material having a density of at least 2.5 g/ml, where the particles of the particulate material have an average diameter of 5-75 mu m, and the particles of the particulate material are essentially constructed of a polymeric base matrix, e.g. a polysaccharide such as agarose, and a non-porous core material, e.g. steel and titanium, said core material having a density of at least 3.0 g/ml, said polymeric base matrix including pendant groups which are positively charged at pH 4.0 or which are affinity ligands for a bio-molecule. Possible pendant groups include polyethyleneimine (PEI), diethylaminoethyl (DEAE) and quaternary aminoethyl (QAE). The materials are useful in expanded bed or fluidised bed chromatography processes, in particular for purification of bio-macromolecules such as plasmid DNA, chromosomal DNA, RNA, viral DNA, bacteria and viruses. |
