Celliance™ Introducing Serum-Free Hybri-Cyte™ To Portfolio Of Cell Culture Products

Serologicals Corporation (NASDAQ: SERO) announced today that Celliance Corporation, its wholly-owned subsidiary, is announcing the introduction of Hybri-CYTE™, a serum-free cell culture supplement designed and optimized for use in hybridoma cell culture that has been proven to work with mouse, rat and rabbit derived cell-lines.

Hybri-CYTE™ is the first of Celliance's new line of serum-free cell culture supplements, each designed and optimized for the most commonly used cell lines in research and bioprocessing. These new supplements eliminate the use of fetal bovine serum and incorporate a number of Celliance's proprietary cell culture products such as EX-CYTE® growth enhancing media supplement, Probumin™ BSA and Incelligent™ Animal Free insulin. Later this year Celliance will release Onco-CYTE™, for use with cancer and HeLa cell culture. Additional products designed for use with CHO and HEK293 cell lines are in development.

David L. Bellitt, President of Celliance, stated, "Our new product line is being developed in response to our customers' increasing demand for cell culture supplements that do not contain fetal bovine serum. A bioprocessor can eliminate the use of fetal bovine serum in one of the most common cell culture applications by using Hybri-CYTE™. The backbone of our new product is our patented EX-CYTE® product, which is the world's best selling serum-free cell culture supplement. With Hybri-CYTE™, our customer gets a supplement that takes the guess work out of serum-free cell culture."

In addition to the EX-CYTE® family of products, Celliance offers a wide range of products for cell culture and diagnostic applications, including Incelligent™-brand recombinant human insulin and Probumin™-brand application specific grades of bovine serum albumin.

David A. Dodd, President and Chief Executive Officer of Serologicals, stated regarding the introduction of Hybri-CYTE™, "When we created Celliance last fall, its mission was clear. First, we wanted it to extend our proprietary position in the serum-free supplement market by leveraging our strong intellectual property position with EX-CYTE®. Second, we wanted it to build strong brand identity around our unique portfolio of cell culture products. With the introduction of Hybri-CYTE™ and the continued success of our EX-CYTE® evaluation program, which finished the year with approximately 500 evaluations, we believe it is off to an excellent start."

Celliance™ offers an expanding array of bioprocessing products and services including diagnostic products, contract research and manufacturing services, and cell culture media supplements, including EX-CYTE®, the largest selling cell growth supplement, Probumin™, a proprietary line of bovine serum albumin and Incelligent™, the Company's recombinant human insulin. It is also the world's leading provider of monoclonal antibodies for the blood typing industry. CellianceTM is a Serologicals company based in Atlanta, GA.
