ADVISORY...for Wednesday, June 6

VACAVILLE, Calif.--(BW HealthWire)--May 2, 2001

Large Scale Biology Corporation (Nasdaq: LSBC) is pleased to invite journalists and financial analysts to attend the first-ever scientific briefing on the recently completed inventory of proteins in the human body, known as the Human Protein Index(TM) (HPI(TM)). The HPI provides the first important baseline for determining the essential link between genes and the vast array of proteins in human health and disease. The briefing will be held on Wednesday, June 6, 2001 from 9:30 AM to 12:00 PM at the New York Academy of Sciences in New York City.

Dr. Leigh Anderson, chief scientific officer of LSBC commented, "This first version of the Human Protein Index heralds a new era in the study of human anatomy begun with the reawakening of interest in human physiology in the 1400's. For the first time, scientists have a meaningful way to relate the function of the broadest array of proteins to their roles in disease and treatment. In fact, many of the discovered proteins have not yet been described in scientific literature, and may indeed provide a fascinating, and much more holistic, viewpoint on human health and illness."

"LSBC is pursuing direct health applications of the HPI through an alliance with Biosite Diagnostics, in which we plan to select 2,000 - 5,000 protein targets to be used to create protein chips," said Robert Erwin, CEO of LSBC. "We believe protein chips represent the third, and foreseeably most important technology of proteomics alongside 2-D electrophoreses and mass spectrometry."

The conference will feature a distinguished panel of scientists who will discuss the historic, decades-long search for the human proteome, as well as how the Human Protein Index was developed, its initial findings, and its potential impact on medicine.

DATE: Wednesday, June 6, 2001 TIME: 9:30 AM - 12:00 PM Eastern LOCATION: New
