GENTEL BIOSCIENCES OBTAINS LICENSE FROM AGNITIO

MADISON, WI (August 11, 2008) — Gentel® Biosciences, a protein microarray life sciences
company, announces it has obtained an exclusive license to novel technology for manufacturing
highly-reproducible nitrocellulose protein microarray slides.

The technology, developed by Agnitio Science and Technology of Hsinchu, Taiwan,
covers the use of ultrasonic coating to produce nitrocellulose films. “Ultrasonic coating
produces nitrocellulose films with a consistency unattainable using traditional coating processes
like casting,” stated Dr. Bryce Nelson, Gentel’s VP of Research and Development.

“Additionally,
the technology is extremely flexible and can be used to fabricate optically clear or porous white
nitrocellulose films.”

Gentel plans to incorporate ultrasonic coating technology into its manufacturing process
for standard microarray slides as well as for its recently developed 96-well microarray platform,
APiX 96™.

“The technology is highly scalable and will enable us to manufacture the number and
type of protein microarray slides required for protein biomarker discovery, validation, and
diagnostics,” says G. Randall Durnell, Gentel VP of Commercial Operations.

“The acquisition of
this intellectual property further extends Gentel’s position as the market leading protein
microarray company.”

The ultrasonic coating technology is covered by a suite of issued and pending US and
international patents.
