Bispecifics and how they work

A normal antibody can bind one specific target (i.e. it has one specificity). A bispecific is an engineered protein that is composed of two different antibodies or parts of antibodies that are fused together so that the engineered protein (a bispecific) can bind two different targets at the same time (i.e. it has two specificities).

Imunexus is developing its bispecific technology to make new medicines that are potentially more effective in treating specific diseases.

Imunexus' technology can convert antibodies into bispecifics

The Company’s technology allows it to potentially generate bispecifics directly from existing antibodies or other proteins. An advantage of the Imunexus approach over other existing technologies is that our technology can be applied directly to antibodies or other proteins to “convert” them into bispecifics, confer them with specific additional properties and consequently, improve the antibody’s characteristics.
