IBA Lifesciences

Website »

IBA is one of the foremost providers of TAG-derived products and services for PCR, cloning, transfection, protein expression and purification to detection, immobilization, and T-cell isolation.


Cloning System

 Cloning System - StarGate®

Offers rapid and highly efficient subcloning of an arbitrary gene - initially cloned into a Donor Vector - to simultaneously fuse it with many different genetic surroundings via transfer into Acceptor Vectors to generate destination vectors.

  • Fast recombinant protein expression optimization
  • Systematic screening for different features
  • Flexible fusion of different genes
  • High throughput cloning

Mammalian Expression System

MEXi (Mammalian Expression IBA)

MEXi is an economic mammalian expression system in which all components are geared to each other. It includes a well transfecting expression vector backbone (pDSG-IBA), a HEK293/EBNA cell line (MEXi-293E) adapted to suspension growth, MEXi Culture Medium and MEXi Tranfection Medium. Due to their low biotin content, the cell culture media are perfectly adjusted to the IBA Strep tag®protein purification technology.

The use of mammalian cells for the expression of recombinant proteins, particular of secreted proteins, offers many advantages e.g. accurate protein folding or complex glycosylation. For more information about the MEXi system and for a detailed overview please click here.
