Chromosome microdissection – Wikipedia

The DOP-PCR technique, which is rapid, efficient, and species-independent, is designed to amplify target DNAs at frequently occurring priming sites using the primer of partially degenerate sequence, without restrictions imposed by the complexity or the origin of DNA.

Direct chromosomal microdissection and microcloning is a rapid technique for providing probes for such areas.

Finally, a two-step PCR amplification is performed to select the hybridized fraction of the samples: However, the present state of microdissection and microcloning technique cannot meet the needs for sequencing the complete specific chromosome DNA due to low coverage and small size of inserted DNA fragments.

Zuo Wu Xue Bao. A novel method to isolate the common fraction of two DNA samples: Or, a portion of a chromosome may be repeated over and over again, resulting in an unusually wide, dark band known as a homogeneously staining region.

Molecular cloning of DNA from specific chromosomal regions by microdissection and sequence-independent amplification of DNA. Analysis and sorting of chromosmes by flow cytometry: Studies on contamination of cytoplasm DNA and its control in plant chromosome microdissection.

The purpose of this article is to review the development of this technique and its application in the field of genomic research. To construct a high specificity, high coverage and low bias library with larger insert fragments, we only need single chromosome DNA. In order to isolate one special chromosome, Griffin et al. The earliest chromosome microcloning [ 61 ] was a kind of direct cloning of the dissected chromosomal material in a nanoliter microdrop contained in an oil chamber.

However, the introduction of PCR technology to the micro-cloning protocols has brought a substantial improvement in cloning efficiency [ 46 ]. During those 20 years, this technique has not only been benefited from other technological advances but also cross-fertilized with other techniques.

Scientists who study chromosomes are known as cytogeneticists.

This is a good method for the enrichment of ESTs of the specific chromosomes or chromosome fragments [ 1939 ]. The probes usually generate from the clones of cosmid library, yeast artificial chromosome YAC and bacterial artificial chromosome BAC.

Acid Treatment Leads to Depurination One of the major concerns for the successful application of chromosome microdissection and microcloning technique was the extensive depurination of the chromosomal DNA caused by acid treatment during the sample fixation in chromosome preparation [ 14 ].
