Dualsystems Biotech AG is a biotech spin-off company founded in 2000. Our major focus is the development of products and services in the emerging area of proteomics. Our areas of expertise include screening for protein-protein interactions using yeast based systems, expression and purification of recombinant proteins in yeast and E. coli,  solutions for cDNA library construction and a range of specialized reagents and antibodies.

The DUALhybrid screening technology is based on the original yeast two-hybrid system and offers several advantages when searching for novel protein-protein interactions, such as speed, specificity and low cost.

The DUALmembrane system is an extremely powerful screening technology aimed at identifying protein-protein interactions between integral membrane proteins. By circumventing problems associated with traditional screening systems, the DUALmembrane system is used to directly identify interactions between membrane proteins in their natural setting.

The DUALXPress technology is a novel, innovative system to express recombinant proteins in E. coli at very high levels and with a high degree of solubility. The dualTRAP resin is an excellent choice for single-step protein purification because it has a very low non-specific binding capacity.

The EasyClone cDNA library construction kits are suited for quick and easy construction of highly complex cDNA libraries with a high representation of 5' ends.
