notes: label: Description (Brief)
content: This electroelution chamber was used by scientists at Genentech, a biotechnology company, in the late 1970s and early 1980s. Electroelution is a technique for removing proteins and other molecules from the gel matrix of gel electrophoresis.
label: Description (Brief)
content: Sections of the gel containing the desired sample were excised and placed into a piece of dialysis tubing. The tubing was secured to the bottom of the chamber using small clips buried in a layer of modeling clay at the bottom of the chamber. Once tubing was secured, the chamber was filled with a buffer solution. An electric current was run through the chamber, causing molecules of interest to migrate across the dialysis tubing into the buffer, from which they were collected.
label: Description (Brief)
content: The modeling clay was not originally part of the chamber, but was purchased from a toy store and pressed onto the bottom of the chamber by scientists in order to provide a way to secure the clips to the bottom.
