Mass., Feb 29, 2016 -- Xenetic Biosciences, Inc. (OTCQB: XBIO), a biopharmaceutical company developing next-generation biologic

drugs and novel oncology therapeutics, today announced the appointment of renowned chemist and Nobel Laureate, Dr. Roger D. Kornberg

to the Company's Board of Directors.

Kornberg is a member of the U.S. National Academy of Sciences and the Winzer Professor of Medicine in the Department of Structural

Biology at Stanford University. He earned his bachelor's degree in chemistry from Harvard University in 1967 and his Ph.D. in

chemical physics from Stanford in 1972. He became a postdoctoral fellow at the Laboratory of Molecular Biology in Cambridge, England

and then an assistant professor of biological chemistry at Harvard Medical School in 1976, before moving to his present position

as professor of structural biology at Stanford Medical School in 1978.

2006, Dr. Kornberg was awarded the Nobel Prize in Chemistry in recognition for his studies of the molecular basis of Eukaryotic

Transcription, the process by which DNA is copied to RNA. Dr. Kornberg is also the recipient of several awards, including the

2001 Welch Prize, the highest award granted in the field of chemistry in the United States, and the 2002 Leopald Mayer Prize,

the highest award granted in the field of biomedical sciences from the French Academy of Sciences.

on the appointment, Scott Maguire, CEO of Xenetic Biosciences, stated, "It is with great pleasure that Xenetic welcomes

an outstanding talent like Dr. Kornberg to our board. Dr. Kornberg brings to Xenetic the rare combination of large cap board expertise

and intimate knowledge of our science; which will serve the company well as we work to up-list to a more liquid-globally recognized

stock exchange and strive to realize our pipeline's potential as we move to market launch."

Kornberg stated, "I am pleased to assist Xenetic Biosciences in the development of their next generation pharmaceuticals,

which employ methods and materials in my areas of expertise. It is clearly evident that Xenetic's novel technologies offer
