  • Medical Device Link .
    Mediated electrochemical detection of nucleic acids for drug discovery and clinical diagnostics Mediated oxidation of guanine residues is a rapid and sensitive method for the direct detection of nucleic acids. Natasha D. Popovich, PhD, is the manager of electrochemical instrumentation at Xanthon
  • Application Note: Detection of micro air bubbles in DNA analysis machine
    Well known Biomedical device manufacturer located in United States is in development of a new DNA analysis machine. This instrument is used to determine the order of the four bases - adenine, cytosine, guanine and thymine - given from a DNA sample. The machine would be a cost effective solution
  • Medical Device Link .
    conducting methylation analysis studies. Portions of the human genome are referred to as CpG islands because those areas are rich in CpG dinucleotides (i.e., cytosine-deoxyribose phosphates followed immediately by a guanine-deoxyribose phosphate) when compared with their surrounding regions
  • Enzymes Give Plants UV Protection
    differences. DNA is a series of chemical bases--A-G-C-T (for adenine, guanine, cystosine, and thiamine)--that form the alphabet of life. If they get damaged, the code is illegible; too much unreadable code and the plant dies. Plants may respond in several ways to gene damage. "When your car breaks down
  • Medical Device Link .
    hybridized DNA via oxidation of guanine. A signal is observed only when a guanine residue is oxidized. This electrochemical reaction can be undertaken without an intercalator (click to enlarge). ECD is one such alternative method that has been demonstrated in laboratories but has not been successfully
  • Medical Device Link . DNA-chip technologies
    , cytosine, guanine, and thymine. They also discovered that these bases always recur in the same two pairs: adenine with thymine, and cytosine with guanine. Thus, by knowing part of the molecular structure of a specific genetic segment, one can determine the other part. Moreover, these uniquely
  • Medical Device Link .
    pairs can exist chemically, and one additional base pair is now available commercially. The new commercial base pair consists of iso-guanine (iG) and 5'-methyl-isocytosine (iC). The components required to advance the commercialization potential of this base pair, such as triphosphates for enzymatic
  • Medical Device Link . The human genome project: Gateway to managed health
    , the goal of genome scientists is to determine the entire sequence of human DNA to greater than 99.9% accuracy. As mentioned, the human genome is a linear sequence of 3 billion nucleotides, or bases (adenine, cytosine, guanine, and thymidine, denoted by the letters A, C, G, and T), that make up
