BOSTON--(BUSINESS WIRE)--May 29, 2007 - HepaLife Technologies, Inc. (OTCBB:HPLF) (FWB:HL1) (WKN:500625) is pleased to announce a scientific presentation of its cell based PBS-1 technology for potential influenza vaccine production at the "Options for the Control of Influenza VI Conference," to be held June 17-23, 2007, in Toronto, Canada.

Entitled "High titer growth of human and avian influenza viruses in an immortalized chick embryo cell line without the need for exogenous proteases," and presented by K.A. Smith, from Michigan State University, the poster presentation will cover recent research results of the PBS-1 cell line and, among other things, challenges of current influenza vaccine production methodologies, which rely on embryonated chick eggs, and concerns over existing cell lines, which all require the addition of exogenous agents.

The single most important step towards the production of a cell-culture based vaccine against a targeted virus is the ability to grow the same virus in a cell substrate. In recent tests, the Company's patented 'PBS-1' cells, under development for influenza vaccine production, have successfully replicated numerous human influenza virus strains received from the Centers for Disease Control at substantially higher levels than the research community's widely-used current model, primary chick kidney cells.

Importantly, among the viruses successfully tested were three specific strains deemed currently most threatening by the World Health Organization and the U.S. Food and Drug Administration. These viruses were selected for development of the inactivated influenza vaccines prepared for the 2006-2007 influenza season.

In previous tests, the PBS-1 cells on average functioned five times better than primary chick kidney cells, and in some cases, outperformed them by 150-fold. Influenza viruses grown in PBS-1 cells are released into the culture fluid without the n
