dna sequencing applications and Technologies

DNA sequencing is most frequently used to determine genome sequence. An example of this type of application is the human genome project. Five years after the completion of the human genome project, we are seeing its impacts on biomedical research. Several genes have been identied to associate with genetic conditions, including familial breast cancer and colorectal cancer, Alzheimer's disease, myotonic dystrophy, neurofibromatosis

Many emerging science and technological fields rely heavily on DNA sequencing. For instance, nutrigenetics is the study of how our genetic makeup affects our responses to diet. Nutrigenetics plays a central role in explaining the connection between red meat and colorectal cancer.

This dna sequencing application note describes the high-throughput isolation of genomic DNA from different populations of three-spined stickleback as well as from three-spined stickleback eggs using Invisorb DNA Tissue HTS 96 Kit. The results showed that the extracted genomic DNA can be used for high scale genotyping and genotyping of adaptive and ecological relevant genes.

dna sequencing application note by Anagnostics Bioanalysis describes a fast and efficient method to verify hundreds of gene sequences of interest in parallel. Sample preparation through integrated thermocycling, washing, hybridisation and detection is presented.

Mycoplasma testing of cell lines and cell-derived biological products in the EU was recently updated and is now considering nucleic acid amplification test (NAT) beside the madatory broth/agar culture and the indicator cell line test. The combination of the two methods enables highly effecient mycoplasma detection for both cultivable and non-cultivable mycoplasma species.
  • DNA sequencing information is important for planning the procedure and method of gene manipulation.
  • DNA sequencing is used for construction of restriction endonuclease map.
  • dna sequencing is used to find tandem repeats or inverted repeat for the possibility of hairpin formations.
