MorphoSys AG has announced the successful completion of a new proprietary antibody library, HuCAL PLATINUM. Initial results show that the new antibody library, which is approximately three-times larger than the former version, HuCAL GOLD, can provide a more diverse range of fully human antibodies. In addition, the new technology enables the generation of antibodies having higher affinity as well as improved expression rates. The improvements achieved with this next generation antibody library are expected to significantly shorten timelines from antibody discovery to pre-clinical development and result in antibody drug candidates with improved characteristics.

Scientists from the University of Cambridge have found that alemtuzumab, a drug originally developed for leukemia can curb the progression of multiple sclerosis (MS) even reverse some damage caused by the neurological disorder. The drug, a monoclonal antibody, has also been tested for treatment of other immune system disorders. Alemtuzumab targets the cells of the immune system that attack the myelin sheath and the nerve fibers.

Inverness Medical announced the launch of its new 4th generation rapid HIV diagnostic test – Determine HIV-1/2 Ag/Ab Combo – at the International AIDS Conference (AIDS 2008) in Mexico City. Capable of detecting HIV infection several days earlier than HIV antibody only tests, Determine HIV-1/2 Ag/Ab Combo can, simultaneously and separately, detect HIV p24 antigen (Ag) and antibodies (Ab) for HIV-1 and HIV-2 in human serum, plasma, or whole blood. The lateral flow test will increase the ability to detect and diagnose primary HIV infection, providing clear visual results. Determine can be performed in remote locations where equipments and laboratory facilities are limited. This gives it an edge over lab-based EIA and ELISA 4th generation HIV testing.

New data from an extended follow-up study show that GlaxoSmithKline PLC.’s cervical cancer candidate vaccine, Cervarix, generates sustained high levels of neutralizing antibodies against the two most common cervical cancer-causing virus types for up to 6.4 years. This is the longest duration of sustained neutralising antibody levels reported against both virus types HPV 16 and 18 with a cervical cancer vaccine to date. Experts believe that neutralizing antibodies are essential for protection against cervical cancer.

MorphoSys AG and Sigma Aldrich Corp. plan to cooperate on the design, production and distribution of research antibodies using MorphoSys’ technology. MorphoSys’ AbD Serotec unit plans to develop antibodies against a specific number of targets supplied by Sigma Aldrich, and Sigma Aldrich will offer the antibodies for use in research applications through its online sales platforms.
