Title: Preparation of cells for chromosome analysis
Inventor: CLAUSSEN UWE PROF DR MED
IPC: G01N1/30
Filed: 1997-03-20
Granted: 1998-08-27
Abstract: Preparation of mitotic cells for microscopic chromosome analysis, comprises: (a) applying a hypotonic solution to swell the cells; (b) fixing the cells on carrier for microscopy, and (c) drying the cells. The novelty of the process is that after the hypotonic solution and fixative is applied to the cells, and before the drying process, an acid is applied which is not in solution with another mixture and which has a lower boiling point than water. The acid swells the cells for a second time and is activated by adding water or from the surrounding moisture in the air. Also claimed is an apparatus with a holder for the vessels (2) containing the cell samples for chromosome analysis.  A supply vessel (10) has the hypotonic solution for the first cell swelling before fixing. A further container (12) holds acid and a container (13) has water for the second cell swelling. A pipette assembly (3) transfers the contents of the containers to the sample vessels, and also extracts them from the sample vessels by suction.
