Products and methods for single parameter and multiparameter phenotyping of cells

Procedure for characterization of cells, comprising the steps of: a) providing a suspension of cells in a liquid medium, including said first cells, b) contacting a group of first beads with said suspension being coated each of said first beads with a binding substance or being magnetic so that each first bead is adapted to bind to at least one of said first cells, c) incubating said first beads with said suspension for a period of time effective to allow said first cells to bind to said first beads and form first bead-first cell, each complex first bead-first cell comprising a first bead and a first cell, d) separating said first bead-first cell complexes from said suspension by filtration through a filter, and transferring to a glass slide said first bead-first cell separated by said filtration, and e) examining said first bead-first cell and characterizing said first cells.
