Bioreagent delivery services

We manufacture small to bulk quantities of high quality mAb’s, membrane receptors, enzymes, SARS-Cov2 spike proteins, etc. All our proteins are expressed in cultivated animal cells. They are intended for R&D use for a wide range of in-vitro and in-vivo applications, but not for human use.

Our bioreagents - mostly recombinant proteins - are provided with the highest purity and reliability. They are intended for many applications, and are ideal as raw materials for diagnostics and analytics. Our bioreagents apply to projects within biotech and pharmaceutical organizations, biomedical research units, academic and public research institutions and laboratory centers.

Tailored protein expression and manufacturing

Our Protein Expression Team offers to you a tailored service for the expression of proteins, based on a variety of animal cells in culture – CHO 4Tx®, HEK 4Tx® and Fly4Tx® cells. We cover all activities from the encoding nucleic acid to the manufacturing of a clinically relevant biologic, such as mAb’s (IgG1, IgG2, IgG3, IgG4, IgE, IgA, IgM subclasses), complex enzymes and novel fusion proteins, Fab’s, ScFv’s, diabodies, etc…

Our mammalian expression vectors together with the high yield of our Transient Gene Expression technology, can help you to manufacture difficult to express proteins in support of early in-vitro studies or for late stage pre-clinical assessment of recombinant biologicals – our experts will provide competent advice towards fast phase I/II product entry.

Depending on the stage of development and/or the quantity of protein desired, our Protein Expression Services will select the best method:


We can help you solve complex biological problems through scientific, technical and legal advice in the life science field. We are a team of veteran managers and scientists, active for more than 30 years in the biopharmaceutical industry.
