Abstract
The cytogenetic chamber includes a chamber enclosure, a drying cavity in the enclosure, a door and a hand-insertion port through the door. A slide-supported, fixative-treated cell (prepared outside the chamber or in situ in the chamber) is in the drying area and air flows through the entirety of the drying area at a substantially uniform (and relatively low) flow rate. The fixative dries at substantially the same drying rate, irrespective of the location of the slide in the drying area. 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.
