Limerick, PA. January 28th, 2015 – Rockland Immunochemicals Inc. today announced that it has acquired a minority interest in Abzyme Therapeutics, LLC (Abzyme). Abzyme’s unique technology, designed to develop therapeutic antibodies, comes as an interest to Rockland after the two companies worked together on several former and ongoing National Institute of Health (NIH) funded projects.

Abzyme’s technology, Self-Diversifying Antibody Library (SDALib), advances yeast based monoclonal antibody discovery and optimization by developing a rapid, inducible, self-diversifying VH and VL yeast based library. This will replace the time consuming iterative static library commonly used. One of the key advantages of the Abzyme technology is its ability to continually maturate and optimize antibodies or proteins during the clonal selection process. The process begins with a naïve yeast display that contains genes for antibodies from a number of host organisms. After an initial selection process, the affinity or binding properties of the antibody can be maturated through a proprietary library diversification technology. Once selected, the antibody encoding genes can easily be transferred into an E. coli or other expression hosts to manufacture the desired antibody.

“Abzyme is an exciting company in which we have invested,” explains Rockland’s Chief Operating Officer, Richard Smith. “The pre-existing synergies between Rockland and Abzyme allow us to implant our footstep into the thriving diagnostic and therapeutic antibody markets. We are eager to help advance this established business and make lasting impressions on the future of therapeutic medicines.”

While both companies will remain independent, Rockland has also licensed SDALib to work on single domain antibodies (sdAbs), also known as Nanobodies, which will benefit the research antibody market. Rockland will begin to produce research sdAbs to support important research for cancer and epigenetic targets. Single-domain antibodies have a selection process that is different than traditional monoclonal antibodies and they are about one-tenth the size of a typical antibody. Their small size, physical properties and ease of manufacture can mean significant improvements in the development of important immunoassays. These reagents are expected to be a strong complement to Rockland’s existing polyclonal and monoclonal product lines.
