Polyplus-transfection is a research-focused biotechnology company developing and marketing innovative solutions for transfection and therapies based on nucleic acid delivery. 

 
Technology 

Transfection allows the introduction of nucleic acids, such as a gene or small interfering RNA (siRNA), into cells using chemical compounds. The technique is widely used in experimental research and in protein production.
Introducing a gene into a cell nucleus triggers the expression of the corresponding protein. Conversely, transferring siRNA will block the production of a protein.
Inappropriate gene expression is the root cause of numerous diseases. As a result, the ability to control those genes through gene therapy or RNA interference opens up new therapeutic approaches where efficient intra-cellular drug transfer is key to success.

 
Research & Development 

Using its know-how in nucleic acid delivery, the R&D department at Polyplus-transfection is focused on the development of innovative synthetic compounds designed to take account of the latest advances in the transfer of biomolecules, especially the in vivo delivery of small interfering RNA. Polyplus-transfection is one of the technology leaders in the transfection market.
Polyplus-transfection has established a number of R&D partnerships with biotechnology companies involved in therapeutics. It also plays an active role in European research networks such as GIANT (Gene therapy, and Integrated Approach to Neoplastic Treatment) and RIGHT (RNA Interference Technology as Human Therapeutic Tool).
Polyplus-transfection recently extended its field of expertise to the development of new cationic oligonucleotides, ZNA™, for molecular biology and diagnostics.

 
Product Portfolio 

Polyplus-transfection has been selling its products and services through an international distribution network since 2001. Its customers include biotechnology companies, big pharma and research laboratories. The company established a sales subsidiary in the USA in 2006.
The company also offers high quality consultancy and personalized scientific assistance. Polyplus-transfection has given a high priority to quality management since 2002 when it acquired the ISO 9001:2000 certification.
Polyplus-transfection markets transfection agents for research:
o jetPEI™: in vitro gene transfection
o in vivo-jetPEI™: in vivo nucleic acid transfection
o Fecturin™ : protein and virus production in synthetic media
o INTERFERin™: in vitro siRNA transfection 
o FectoFly™: in vitro transfection in insect cells
o PULSin™: in vitro delivery of proteins, antibodies and peptides
Polyplus-transfection also offers GMP-compliant reagents. The company has acquired a widely-acknowledged expertise in the regulatory and technical issues regarding clinical trials using its products. Such trials are currently being carried out in Israel and the USA (cancer therapeutics) and in Hungary, Sweden and Germany (HIV immune therapy). 

 
Current developments 

o Setting up of the Polyplus in vivo Consortium, an international network, run by Polyplus-transfection, for scientists and clinicians using Polyplus-transfection compounds in gene therapy. The network aims to encourage and accelerate the development of new clinical projects.
o Development of a novel design of siRNA in order to improve siRNA delivery in vivo, the “STICKY SIRNA™”. By including longer overhangs, the STICKY SIRNA™ (ssiRNA™) are able to form concatemers in the presence of in vivo-jetPEI™, thereby mimicking the structure of DNA and thus enhancing siRNA delivery (Bolcato-Bellemin (2007) PNAS 104:16050).
o Development of a new class of modified oligonucleotides, ZNA™, which show a greater affinity for nucleic acids than standard oligonucleotides. By enhancing the sensitivity and the efficiency of hybridization, these versatile ZNA™ are new promising tools for nucleic acid detection methods and for molecular diagnostic applications.
