The OrthoMab technology can generate bispecific antibodies from any two existing antibody sequences. OrthoMab antibodies are produced with standard antibody production and purification techniques, obviating the need for poorly behaved antibody fragments (i.e. scFv) or complicated post-processing purification steps. Through a suite of bispecific antibody formats that vary critical molecular properties, lead agents can be tailored to specific target biology and mechanisms of action.


How does the OrthoMab technology work?

OrthoMab consists of a collection of antibody mutations clustered in two regions of the antibody scaffold. The first set of mutations lies within the Fab region of an antibody, and facilitates the correct formation of two different Fab sequences.  The second set of mutations creates a heterodimer interface within the Fc domain, causing two heavy chains to correctly assemble into a single molecule

The OrthoMab technology allows for generation of a wide variety of bispecific formats that can be tailored to address the unique requirements dictated by target and disease biology


What is needed to start a Collaboration with Dualogics?

Any two antibody sequences can be combined with OrthoMab to create a bispecific antibody.  Dualogics has created bispecific antibodies using variable domains derived from a variety of libraries and host species.  

How are OrthoMab antibodies produced?

OrthoMab antibodies are produced in mammalian cells by transfecting the DNA for each unique antibody chain into a single cell, similar to how traditional monoclonal antibodies are produced. Our technology allows for the correct product to assemble inside the cell and be secreted. These molecules are compatible with single stable cell line production and standard purification methods (e.g. Protein A-based purification).


OrthoMab has been validated in a number of peer-reviewed scientific publications. Check below for a list of publications that use OrthoMab.
