1.3. DNA hybridization in solution of H2O2

    H2O2 has strong corrosion. There was a risk that DNA strand is denatured by H2O2[1]. So, we had to ensure that the hybridization of DNA does not suffer from H2O2. We guessed that if DNA had been destroyed, then molecular mass would decrease in that DNA can't hybridize. Visualizing the relative magnitude of the molecular weight by electrophoresis, we are able to examine whether DNA can hybridize or not.
    This time, we have to examine the state of the DNA in the time we need to steer rocket, set the time to soak and concentration of H2O2. We used PAGE electrophoresis to ascertain the stability of DNA duplex in thin H₂O₂ solution 1%-5%. PAGE electrophoresis shows the difference of molecular weight that comes from dissociation or hybridization in the form of bands.
