Electrophoresis
a: Electrophoresis gel ~
b: a kitchen sponge
What: "The gel serves as a solid mesh to support the biological sample as is it separated by the electrical field. The gel is like a kitchen sponge, but with a microscopic network of holes and connections. For DNA samples, generally a gel is made like you would make jell-o, by heating up a polymer (agarose) with liquid, poring it into a mold, and allowing the network to solidify. (Fun fact: agarose is made from seaweed, and is actually in some products like toothpaste and gummy snacks!) For protein samples, generally a finer network (smaller holes) is required, so a gel is made of a different polymer (acrylamide).

METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
