Modulable Southern and Northern blot hybridization apparatus for routine screening of gene amplification and expression.

An apparatus for Northern and Southern blot hybridization is described. It allows from one to twenty-four blots to be processed at the same time, with different probes. All the pre-, post- and hybridization steps are performed without handling the filters and the experimenter is totally protected from beta radiations. The development of such modulable materials has become necessary since Southern and Northern techniques are becoming routine assays in hospitals, particularly in the field of oncology, in prognosis and for hereditary diseases, as an antenatal diagnosis procedure.
