Alpha Innotech Announces Attainment of Key Milestones.

SAN LEANDRO, Calif. -- After completing the reverse merger with Xtrana on October 3, 2005 Alpha Innotech Corp. (OTCBB:APNO) today announced completion of the following key milestones:

--As previously announced, Alpha Innotech entered into a development, manufacturing and supply agreement with GE Healthcare for a full line of proprietary imaging systems. GE is exclusively selling these products worldwide under their brand name in the life science research market. Alpha Innotech initiated shipments of products in the third quarter of 2005 and will see increasing revenues from this agreement in the fourth quarter.

--First shipments were made of the new AlphaScan(TM) microarray scanner, a compact high performance slide-based scanner for microarray imaging and data analysis of DNA, protein, cell and tissue arrays.

--First shipments were also made of the new NovaRay(R) Detection Platform, designed to address the growing number of applications in the microarray market, including multiplexed arrays (few targets--many samples) for high throughput analysis of DNA. NovaRay can also be used to perform protein and cell array analyses in microplates and on other substrates.

--Introduced AlphaPart11Ease(TM), an innovative and comprehensive software package that enables digital image acquisition and analysis compliant with the electronic validation, audit trail, record retention, and record copying requirements of FDA regulations promulgated under 21 CFR Part 11.

--Following completion of the previously announced reverse merger transaction on October 3, 2005, trading began on the NASD Over-the-Counter Bulletin Board under the symbol APNO:BB. As of November 14, 2005, approximately 9,726,000 common shares were outstanding.

According to Haseeb Chaudhry, Chief Executive Officer of Alpha Innotech, "Key components of our growth strategy include extension and expansion of existing distribution channels and the introduction of new products. The recently announced OEM agreement with GE Healthcare and the introduction of new products such as the NovaRay and AlphaScan systems are the first steps toward attaining this goal. We anticipate sales for the new products to be modest in 2005 and becoming a larger contributor to revenues in 2006."

Mr. Chaudhry added, "With our new growth initiatives and product launches, combined with the increasing interest in drug development and life science research, we anticipate 2006 to be an active year for the company. We hope to strengthen the company and build shareholder value as we move forward into the new year."
