The Report 'Comparative Genomic Hybridization: Current State and Future Directions' Explains the Technology, Assesses Its Limitations and Challenges and Compares It to Prevailing Analytical Approaches.


DUBLIN, Ireland -- Research and Markets (http://www.researchandmarkets.com/reports/c44580) has announced the addition of Comparative Genomic Hybridization hybridization /hy·brid·iza·tion/ (hi?brid-i-za´shun)

If you've not yet heard of Comparative Genomic Hybridization (CGH CGH Comparative Genomic Hybridization

 into the clinic. Peggy Eis, PhD, director of the array CGH business at NimbleGen contends that "Information from SNPs is not the only way to look at the genome." Copy Number Polymorphisms (CNPs) will become a valuable tool for defining relative phenotypes in a population. CGH will eventually play a significant role in the $10 billion molecular diagnostics market, not least in tracking the pathogenesis of, and detecting and monitoring cancer.

A survey (N=66) conducted by the author in August 2006 of individuals involved with CGH at biopharmaceutical and diagnostic firms, vendors of equipment and services, and academic research departments sheds light on current practices and future directions in the use of CGH in pharmaceutical R&D. Among the highlights:

-- Cancer leads all other CGH applications in both basic research and in the clinic

-- 94% of respondents believe that CGH will become a routine part of clinical testing within the next 5 years, with 42% predicting a 2-year time frame.

A surge in the use of CGH will not only benefit life science researchers - it will also provide tool vendors with an opportunity to sell specialized arrays and other technologies for whole genome profiling. Comparative Genomic Hybridization: Current State and Future Directions profiles the major vendors and their CGH product offerings. The report concludes with in-depth interviews with experts in industry and academia, providing authoritative insight into the scientific, medical and commercial aspects of CGH.
