Abstract
The invention relates to a product to permit separation of cells in the domain of immunopurification and consisting of a finely divided carrier of a density lower than that of the medium from which such cells must be extracted, such carrier being covered with macromolecules capable of being specifically fixed to the cells to be extracted to which a priviliged orientation was given to enable fixation of such macromolecules.
Claims11
A product for the extraction of cells or viruses from a biological medium, comprising beads, having a size between 50 and 500 micrometers, said beads having a density lower than unity and being coated with antibodies capable of antigenic binding to cells or viruses to be extracted from the binding of medium, said antibodies being oriented so as to permit binding of said cells or viruses thereto, and said beads being capable of floating upon the surface of the biological medium when antigenically bound to said cells or viruses to be extracted.
A product for the extraction of cells or viruses from a biological medium, comprising beads, having a size between 50 and 500 micrometers, and being coated with a substance capable of specifically binding to the cells or viruses to be extracted, said beads having a size and density sufficient to permit the beads to float upon the surface of the biological medium in which the product is to be used when bound to the cells or viruses to be extracted.
