Cerus Corporation to Present at American Association of Blood Banks Annual Meeting

October, 19 2006

CONCORD, Calif.--(BUSINESS WIRE)--Oct. 19, 2006--Cerus Corporation (NASDAQ:CERS) announced today that the company's INTERCEPT Blood System will be featured at the annual meeting of the American Association of Blood Banks (AABB) being held in Miami, Florida, October 21st - 24th.

Cerus' pathogen inactivation programs will be highlighted during one oral and six poster presentations covering the INTERCEPT platelet, plasma, and red blood cell systems. The INTERCEPT Blood System, which is based on Cerus' proprietary nucleic acid crosslinking technology, is designed to enhance the safety of donated blood components by inactivating viruses, bacteria, and parasites, as well as potentially harmful white blood cells.

"We're pleased to share our progress with the blood banking community at the AABB meeting," said Claes Glassell, president and chief executive officer of Cerus. "Our seven presentations, in addition to the 20 presentations last month at the International Society of Blood Transfusion congress underscore the promise to potentially transform blood safety."

Cerus' oral presentation at the meeting, Abstract #503, will take place on Tuesday, October 24th at 3:00 p.m. Researchers will describe the INTERCEPT system's potential to inactivate pathogens in red blood cells while maintaining critical red blood cell functions. Presented data will compare treatment methods with previous inactivation processes.

Cerus will also present two abstracts on the INTERCEPT red blood cell system during the conference poster presentations, beginning Saturday, October 21st at 9:00 a.m. Abstract #451 describes the modified treatment process used to inactivate pathogens in red blood cells with the INTERCEPT Blood System, and presents data on bacterial and viral inactivation following treatment. Abstract #510 presents evidence for the absence of immunoreactivity to red blood cells treated with the modified INTERCEPT red blood cell system in non-transfused patient serum samples.

Cerus researchers will also present two posters on the company's INTERCEPT plasma system, also beginning Saturday, October 21st. The first, Abstract #584, compares therapeutic levels of coagulation factors in INTERCEPT plasma prepared from fresh plasma and from fresh frozen plasma, Abstract #361 describes therapeutic levels of coagulation factors in INTERCEPT plasma following extended periods (up to 18 months) of cold storage.

Also during the Saturday poster presentation, Cerus will present two additional studies on the INTERCEPT Blood System. Abstract #317 discusses the use of the INTERCEPT platelet system to inactivate pathogens in donor platelets during a recent epidemic of the Chikungunya virus. Abstract #416 describes the use of the INTERCEPT Blood System to inactivate pathogens in platelets and plasma, and presents data on reductions of harmful bacteria and viruses following treatment.

The abstracts discussed above are currently available in Transfusion September 2006 - Vol. 46 Issue 9s Page 1A-267A. You may also obtain a copy by visiting www.cerus.com beginning September 21st.
