DNA purification

This is 3 of 12 in a series on protein engineering. These are illustrations I made in high school for a senior project presentation combining art & biotechnology. I spent a year interning in a biochemistry lab at KU Medical Center.

After mutant plasmids are successfully made, the DNA must be purified from the fragments of original plasmid and other irrelevant stuff floating around. P1, P2, N3, & PE are solutions used to wash those things out through the microbead filter.
