We are delighted to have worked with Chris Thornton and the team at ISCA Diagnostics

UK based contract research organisation Fusion Antibodies and UK medical diagnostics company ISCA Diagnostics, have today announced the successful completion of the humanization of the Aspergillus-specific monoclonal antibody JF5. The project was completed ahead of schedule and with outstanding results.

The JF5 humanization project is the most recent in a series of successful projects for Fusion Antibodies and is a case study example of the robust nature of Fusion Antibodies’ CDRx humanization platform. Fusion Antibodies have been able to prove that is CDRx Humanization platform maintains the binding affinity of the parental JF5 antibody. As the ELISA data shows, high titres of the three clones are displayed against the target mannoprotein antigen when compared with mouse antibody from the parent hybridoma JF5, with target recognition maintained at the picogram/ml level.

Paul Kerr, Managing Director at Fusion Antibodies commented: “We are delighted to have worked with Chris Thornton and the team at ISCA Diagnostics and are excited for the future of the humanized JF5 antibody”. Chris Thornton of ISCA Diagnostics added: “The humanized antibody will now enter cGMP production for use as a theranostic agent for diagnosis and therapy of invasive pulmonary aspergillosis in humans. The production by Fusion Antibodies of a highly sensitive and specific humanised version of the JF5 antibody for ISCA places us at the forefront of the fight against this devastating disease of immunocompromised patients. This ground breaking work opens up highly novel opportunities for early detection and treatment of the disease.” Fusion Antibodies will now transfer all materials to ISCA Diagnostics for commencement of work package 2 in the MATHIAS programme.
