Zytogenetische Kammer und Verfahren für seine Anwendung

摘要

The cytogenetic chamber (10) includes a chamber enclosure (23), a drying cavity (31) in the enclosure (23), a door (33) and a hand-insertion port (37) through the door (33). A slide-supported, fixative-treated cell (11) (prepared outside the chamber (10) or in situ in the chamber (10)) is in the drying area (43) and air flows through the entirety of the drying area (43) at a substantially uniform (and relatively low) flow rate. The fixative (12) dries at substantially the same drying rate, irrespective of the location of the slide (39) in the drying area (43). A related method is also disclosed. The invention is particularly useful for chromosome spreading and results in a significantly-increased percentage of metaphases having metaphase areas in the optimal range of 2,500 to 4,500 squared microns.
