Sau 3AI

Description (Brief)
This silver metal canister once contained Sau 3AI, an enzyme commonly used in molecular biology. Sau 3AI belongs to a class of enzymes known as restriction enzymes, which are useful for their ability to cleave DNA only at locations containing specific sequences of nucleotides, the small chemical units which make up the longer DNA molecule. Sau 3AI recognizes the sequence GATC and will cut before the G.
This particular canister of Sau 3AI was used to create recombinant DNA molecules at Genentech, a biotechnology company, in the early 1980s.
