Finally, after the DNA, RNA, or protein molecules have been separated using gel electrophoresis, bands representing molecules of different sizes can be detected.

Once the transfer is complete, the membrane carries all of the protein bands originally on the ... to their sizes using a method called gel electrophoresis. Following separation, the proteins ...

This abrupt slow-down concentrates the genomes in a sharp band that confirms that the ... the 10-minute runs are very fast compared to gel electrophoresis, polymerase chain reaction (PCR), or ...
