CONTROLLED PRINTING OF A CELL SAMPLE FOR KARYOTYPING

摘要

Methods and techniques for controlled printing of a cell sample for karyotyping are provided. The methods can involve matrix printing using on-the-fly printing or dispensing to accurately spread cells within at least one cell sample on a surface in preparation for karyotyping, and further analysis. Advantageously, the methods result in a uniform distribution of chromosomes of the cell suspension or sample on the surface of a substrate which can be substantially discretely identified, and also provide for efficiency in a subsequent staining process and any further analysis of the stained chromosomes using a microscope or other imaging device.
