 a few years later. When he was a young boy, he began inventing devices. "It was stimulating to see chemicals change the color of fluids, to construct crystal radios, and to make caramel from sugar—however, my mother’s pots and pans were never the same afterward. It seemed that I constantly thought about new ideas to implement. As a teenager I developed an electronic security key and many other devices, but I did not know about patents at that time." Both his parents encouraged his curiosity; his mother taught him mathematics when he was very young and his father shared his own hobby of building bicycles with basic parts.

In 1957, he graduated summa cum laude from Princeton University

Research

While in the Nirenberg Laboratory, he discovered how the genetic code of the
mRNA is translated into protein through the small ribosomal subunit

The term is sometimes used to refer only to protein translation but more often it refers to a multi-step process, beginning with amino acid synthesis and transcription of nuclear DNA into messenger RNA, which is then...

, where for three years he continued his research on protein synthesis, and began investigations in other areas. It was here that he first learned about interferons. Scientists first observed interferon in the 1950s, and when they learned that human cells secreted the substance it was postulated that interferon could hold the key to beneficial antiviral properties. Pestka became very interested in interferon.

For the next 16 years, he worked ways to produce clinically relevant quantities of interferon at reasonable cost. Among other advances, he developed reversed phase HPLC for the purification of proteins. Until that time, it was believed that reversed phase HPLC would denature proteins. He also developed the procedure to clone interferons. These advances led to the first recombinant biotherapeutic, alpha interferon.

Work

Since 1986, he has been Professor and Chairman of the Department of Molecular Genetics, Microbiology and Immunology at UMDNJ-Robert Wood Johnson Medical School in Piscataway, New Jersey. He is also the Founder and Chief Scientific Officer of Pestka Biomedical Laboratories in Piscataway.

Patents

While at the Roche Institute of Molecular Biology, he generated a large portfolio of groundbreaking patents for Hoffmann-La Roche. In 1993, he was inducted into the New Jersey Inventors Hall of Fame. His work is the basis for a number of U.S. and foreign patents. Interferon is a major product of several U.S. and foreign companies many of which
