Products for separation applicable to cells in the immunopurification field

摘要

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.
