Labelling for Photo-Regulation ofOligonucleotides

Photo-control, the use of ultraviolet or visible light to control a reaction,has a number of advantages over other external stimuli:

  • Light does not introduce contaminants into the reactionsystem,
  • Excitation wavelength can be controlled through the design ofthe photo-responsive molecule
  • It is now straightforward to control irradiation time and/orlocal excitation.

When a photo-responsive molecule is directly attached to DNA as a receptor,photo-regulation of the bioprocess regulated by that DNA molecule could, inprinciple, be achieved. Such photo-responsive DNA could also be used as a switchin a DNA-based nano-machine. Professor Hiroyuki Asanuma and his group at thedepartment of Molecular Design and Engineering of the Graduate School ofEngineering of the Nagoya University (Japan) have developed an efficient methodto achieve this goal. They have attached azobenzene to DNA and made itphoto-responsive1,2. Azobenzene is a typical photo-responsivemolecule that isomerizes from its planar trans-form to the non-planar cis-formafter UV-light irradiation with a wavelength between 300 nm and 400 nm (lmax isaround 330 nm). Interestingly, the system reverts from the cis-form to thetrans-form after further irradiation with visible light (wavelength over 400nm). This process is completely reversible, and the azobenzene group does notdecompose or induce undesirable side reactions even on repeated trans-cisisomerization. By introducing azobenzenes into DNA through D-threoninol as alinker, Asanuma and co-workers succeeded in achieving photo-regulation of:

  • Formation and dissociation of a DNA duplex3,4 and
  • Transcription by T7-RNA polymerasereaction5,6,7.

Myeloperoxidase Enzyme Immunoassay Kit 髓过氧化物酶 免疫分析试剂盒 Human MPO EIA KIT FEATURES: USE - Measure human MPO in a variety of matrices SAMPLE -Serum, Platelet-Poor Heparin Plasma, Saliva, Urine or Tissue Culture Media SAMPLES / KIT - 40 in duplicate SENSITIVITY - 0.068 ng/mL STABILITY - liquid reagents stable at 4°C QUICK RESULTS - 2.5 HOURS Myeloperoxidase (MPO) is a tetrameric heme-containing protein abundantly produced in neutrophil granulocytes where it plays an important anti-microbial role. During degranulation MPO is released into the extracellular space. There, as part of the neutrophils “respiratory burst”, it produces hypochlorous acid from hydrogen peroxide and Cl–. MPO also uses hydrogen peroxide to oxidize tyrosine to the tyrosyl radical. Both hypochlorous acid and tyrosyl are cytotoxic and when present can kill bacteria and other pathogens. Hereditary deficiency of myeloperoxidase predisposes individuals to immune deficiency. Studies have shown an association between elevated MPO levels and coronary artery disease, and in 2003 it was suggested that MPO may serve as a sensitive predictor of myocardial infarction in patients complaining of chest pain. Since that time the clinical utility of MPO testing in cardiac patients has been solidly established in the literature with well over 100 papers published. In 2010 this clinical application was further refined by additional studies which determined that measuring both MPO and C-reactive protein (CRP) provided more accurate prediction of mortality risk than measuring just CRP alone.
