  • Specification
  • Product Description:
  • Labeled FISH probes for identification of gene amplification using Fluoresecent In Situ Hybridization Technique.
  • Quality Control Testing:
  • Representative images of human breast cancer cell stain with the dual color FISH probe. The left image is two copies of TOP2A gene and two copies of chromosome 17 in cell (normal); and the right image is two copies of chromosome 17, higher copy number of TOP2A gene (amplificaton).

  • Gene Description:
  • topoisomerase (DNA) II alpha 170kDa
  • Gene Summary:
  • This gene encodes a DNA topoisomerase, an enzyme that controls and alters the topologic states of DNA during transcription. This nuclear enzyme is involved in processes such as chromosome condensation, chromatid separation, and the relief of torsional stress that occurs during DNA transcription and replication. It catalyzes the transient breaking and rejoining of two strands of duplex DNA which allows the strands to pass through one another, thus altering the topology of DNA. Two forms of this enzyme exist as likely products of a gene duplication event. The gene encoding this form, alpha, is localized to chromsome 17 and the beta gene is localized to chromosome 3. The gene encoding this enzyme functions as the target for several anticancer agents and a variety of mutations in this gene have been associated with the development of drug resistance. Reduced activity of this enzyme may also play a role in ataxia-telangiectasia. [provided by RefSeq
