Abstract:
The two synthetic self complementary oligonucleotides pd(AT)12 and pd(GC)12 were separated by free solution capillary electrophoresis (CZE) using simple borate buffers. The effects of pH (7.5-9) and the concentration of the buffer (0.03-0.35 M) were investigated. Higher pH values and buffer concentrations led to better resolution and longer migration times, the pH having a more pronounced effect on the separation than the concentration of the buffer. It is proposed that the conformation and effective length of the oligonucleotides may have a role in their separation in free solution capillary electrophoresis.

SDS-PAGE
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...
