Abstract:
Silver staining of nucleic acid has been widely used in molecular marker analysis such as simple sequence repeat (SSR), single-strand conformation polymorphism (SSCP), and amplified fragment-length polymorphism (AFLP). Many alternatives to silver staining methods have been described, but these methods are not efficient or cost-effective. Here we report a silver staining method that requires less than 10min for one gel and can save chemicals as well. It has a detection limit of approximately 5.6pg of DNA/mm(2) in nondenaturing polyacrylamide gels and 12.8pg/mm(2) in denaturing polyacrylamide gels.

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...

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...
