Abstract:
A practical, sensitive and environment-benign protocol for the detection of DNA on polyacrylamide gels was described. In this method, the most commonly used formaldehyde-based developer in DNA silver stain, which poses potential hazards to the health of operators, is firstly replaced by vitamin C (Vc) in sodium thiosulfate solution. This allows user-friendly and efficient visualization of DNA that takes about 20 min to complete all the procedures, and provides comparable sensitivity (8 pg of single band) to the most sensitive formaldehyde-based silver staining method developed before.

A variation of gel electrophoresis, termed polyacrylamide gel electrophoresis (PAGE), is commonly used for separating proteins according to their molecular size by passing them through a polyacrylamide gel. Because of the varying charges associated with amino acid side chains, PAGE can be used to separate intact proteins...

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...
