Abstract:
The enhancement of the Resonance Light Scattering (RLS) due to Victory blue-B on the molecular surface of DNA in alkalescence solution was studied. A method of resonance light scattering was developed to determine DNA. Deoxyribonucleic acid (DNA) was studied in the range of pH 9.0-10.5. The effects of interference substances and optimization of procedure were investigated and a new method was established for the determination of DNA at nanogram level based on RLS measurement. The linear range of the DNA is 0-3.0 mg x L(-1) with a correlation coefficient of 0.9978. The detection limit is 21.5 microg x L(-1). The method has been applied to the determination of DNA in mixed samples with satisfactory result.

Labeling DNA Probes
Radioisotopes, fluorophores, or small molecule binding partners like biotin or digoxigenin, are the most widely used reporter tags for labeling DNA probes. These labels can be attached to the probe DNA molecule via...
Southern Blot
Denatured DNA fragments must be transferred onto a carrier membrane from the gel to make it accessible to a probe - a small ssDNA fragment complementary to the target DNA...
DNA Agarose Gel Electrophoresis
Gel extraction follows five major steps: running gel electrophoresis to separate fragments, isolating the individual bands, extracting DNA from those bands, and removing the dye and salts from the extracted mixture to obtain pure DNA.
In cloning experiments, both the insert and vector DNA...
