TLDR
In this article, a reverse chromosome painting method is proposed to detect chromosome duplications in short-term blood culture preparations or cell lines by using bivariate flow karyotype analysis.
Abstract
We describe a method, termed reverse chromosome painting, which allows the rapid analysis of the content and breakpoints of aberrant chromosomes. The method involves the sorting of small numbers of the aberrant chromosome from short term blood culture preparations or cell lines by using bivariate flow karyotype analysis. The sorted chromosomes are amplified and biotin labelled enzymatically using a degenerate oligonucleotide-primed polymerase chain reaction (DOP-PCR), the product annealed to metaphase spreads from normal subjects, and hybridisation detected using fluorescence in situ hybridisation (FISH). We show the usefulness of this method for routine clinical cytogenetics by the analysis of cases involving an insertion, a deletion, a translocation, and two cases of a chromosome with additional material of unknown origin. The method has particular application for the rapid resolution of the origin of de novo unbalanced chromosome duplications.

Degenerate oligonucleotide-primed PCR: General amplification of target DNA by a single degenerate primer

TL;DR: DOP-PCR represents a rapid, efficient, and species-independent technique for general DNA amplification, and has advantages over interspersed repetitive sequence PCR (IRS- PCR), which relies on the appropriate positioning of species-specific repeat elements.

The new cytogenetics: blurring the boundaries with molecular biology.

TL;DR: Cytogenetic analysis now extends beyond the simple description of the chromosomal status of a genome and allows the study of fundamental biological questions, such as the nature of inherited syndromes, the genomic changes that are involved in tumorigenesis and the three-dimensional organization of the human genome.

A map of the human immunoglobulin VH locus completed by analysis of the telomeric region of chromosome 14q

TL;DR: A map of the immunoglobulin VH locus which accounts for almost all VH segments known to rearrange in B-lymphocytes is completed, demonstrating the importance of combinatorial diversity produced by VDJ joining and the association of heavy and light chains in producing the human antibody repertoire.

A comparative study of karyotypes of muntjacs by chromosome painting

TL;DR: The interspecific chromosomal homology was demonstrated by the use of both enhanced DAPI banding and comparative chromosome painting, providing direct molecular cytogenetic evidence for the tandem fusion theory of the chromosome evolution of muntjac species.

Fluorescence in situ hybridization with human chromosome-specific libraries: detection of trisomy 21 and translocations of chromosome 4.

TL;DR: Chromosomes can be specifically stained in metaphase spreads and interphase nuclei by in situ hybridization with entire chromosome-specific DNA libraries to inhibit the hybridization of sequences in the library that bind to multiple chromosomes.

TL;DR: A method of in situ hybridization for visualizing individual human chromosomes from pter to qter, both in metaphase spreads and interphase nuclei, is reported and should be useful for both karyotypic studies and for the analysis of chromosome topography in interphase cells.
