1992, 1992-1993
Notes:
The Polymerase Chain Reaction (PCR) technique was invented in 1985 by Kary B. Mullis, a chemist at the Cetus Corporation, a biotechnology firm in Emeryville, California. PCR allowed scientists to make millions of copies of a scarce sample of DNA. Although revolutionary, Mullis' technique proved to be slow and labor-intensive, and Cetus scientists soon automated the process with the creation of the first thermocycling machine, MR. CYCLE. In 1985, Cetus formed a joint venture with the Perkin-Elmer Corporation in Norwalk, Connecticut, and introduced the DNA Thermal Cycler. On January 15, 1989, Cetus announced an agreement to collaborate with Hoffman-La Roche on the development and commercialization of in vitro human diagnostic products and services based on PCR technology. The PCR patent and associated technology was later purchased by Roche Molecular Systems

Historical Note

The Polymerase Chain Reaction (PCR) technique, invented in 1985 by Kary B. Mullis, allowed scientists to make millions of copies of a scarce sample of DNA. The technique has revolutionized many aspects of current research, including the diagnosis of genetic defects and the detection of the AIDS virus in human cells. The technique is also used by criminologists to link specific persons to samples of blood or hair via DNA comparison. PCR also affected evolutionary studies because large quantities of DNA can be manufactured from fossils containing but trace amounts.

Kary Mullis invented the PCR technique in 1985 while working as a chemist at the Cetus Corporation, a biotechnology firm in Emeryville, California. The procedure requires placing a small amount of the DNA containing the desired gene into a test tube. A large batch of loose nucleotides, which link into exact copies of the original gene, is also added to the tube. A pair of synthesized short DNA segments, that match segments on each side of the desired gene, is added. These "primers" find the right portion of the DNA, and serve as starting points for DNA copying. When the enzyme Taq DNA Polymeras from the bacterium, Thermus aquaticus is added, the loose nucleotides lock into a DNA sequence dictated by the sequence of that target gene located between the two primers.

The test tube is heated, and the DNA's double helix separates into two strands. The DNA sequence of each strand of the helix is thus exposed and as the temperature is lowered the primers automatically bind to their complementary portions of the DNA sample. At the same time, the enzyme links the loose nucleotides to the primer and to each of the separated DNA strands in the appropriate sequence. The complete reaction, which takes approximately five minutes, results in two double helices containing the desired portion of the original. The heating and cooling is repeated, doubling the number of DNA copies. After thirty to forty cycles are completed a single copy of a piece of DNA can be multiplied to hundreds of millions.

When completed manually, Mullis' PCR technique was slow and labor-intensive. Therefore, Cetus scientists began looking for ways in which to automate the process. Before the discovery of the thermostable Taq enzyme, scientists needed to add fresh enzyme to each cycle. The first thermocycling machine, "Mr. Cycle" was developed by Cetus engineers to address that need to add fresh enzyme to each test tube after the heating and cooling process. Purification of the Taq polymerase then resulted in the need for a machine to cycle more rapidly among different temperatures. In 1985, Cetus formed a joint venture with the Perkin-Elmer Corporation in Norwalk, Connecticut, and introduced the DNA Thermal Cycler. By 1988, Cetus was receiving numerous inquiries about licensing to perform PCR for commercial diagnostic purposes. On January 15, 1989, Cetus announced an agreement to collaborate with Hoffman-LaRoche on the development and commercialization of in vitro human diagnostic products and services based on PCR technology. Roche Molecular Systems eventually bought the PCR patent and associated technology from Cetus for $300,000,000.

Interviewees included scientists, engineers, and managers from Cetus Corporation, Roche Molecular Systems, and Perkin-Elmer Corporation. Norman Arnheim first became interested in the study of medicine in high school, as the result of a summer spent working at a hospital.

Introduction

The Smithsonian Videohistory Program, funded by the Alfred P. Sloan Foundation from 1986 until 1992, used video in historical research. Additional collections have been added since the grant project ended. Videohistory uses the video camera as a historical research tool to record moving visual information. Video works best in historical research when recording people at work in environments, explaining artifacts, demonstrating process, or in group discussion. The experimental program recorded projects that reflected the Institution's concern with the conduct of contemporary science and technology.

Smithsonian historians participated in the program to document visual aspects of their on-going historical research. Projects covered topics in the physical and biological sciences as well as in technological design and manufacture. To capture site, process, and interaction most effectively, projects were taped in offices, factories, quarries, laboratories, observatories, and museums. Resulting footage was duplicated, transcribed, and deposited in the Smithsonian Institution Archives for scholarship, education, and exhibition. The collection is open to qualified researchers.

Ramunas Kondratas, curator at the Smithsonian's National Museum of American History (NMAH), documented the discovery, development, commercialization, and applications of PCR technology. Three sessions were recorded May 14 and May 15, 1992 at Emeryville, California; September 25, 1992 at Alameda, California; and February 25, 1993 at Norwalk, Connecticut.

This collection consists of three interview sessions, totalling approximately 19:00 hours of recordings, and 346 pages of transcript. There are three generations of tape for each session: originals, dubbing masters, and reference copies. In total, this collection is comprised of 38 original Betacam videotapes, 19 dubbing master U-matic videotapes, and 11 reference copy VHS videotapes. The collection has been remastered digitally, with 38 motion jpeg 2000 and 38 mpeg digital files for preservation, and 38 Windows Media Video and 38 Real Media Video digital files for reference.

Several participants were also interviewed on audiotape. The audiotapes and transcripts complement the videotape sessions and are available through the Division of Medical Science, National Museum of American History.
