| abstract |
The invention discloses a magnetic immunoseparation method of cells, particularly of bacteria, foetal cells, bone marrow stem cells and systemic cancerous cells, consisting in fixing target cells on paramagnetic balls and causing a magnetic field to act on a sample containing the fixed cells, the free cells and the supernumerary paramagnetic balls, to isolate the paramagnetic balls. The sample is circulated in a tube (2), the cross-section of which is much less than the length on which the magnetic field is applied. |
