Date Nov. 13, 1997A process for magnetic immunoseparation of cells, in particular bacteria, fetal cells, stock cells of bone marrow and circulating cancerous cells, of the type consisting in affixing the target cells on paramagnetic balls and in causing a magnetic field to act on a sample containing the affixed cells, the free cells and the surplus paramagnetic balls, in order to isolate the paramagnetic balls, in that the sample is caused to circulate in a tube the section of which is much less than the length over which the magnetic field is applied.
