What makes Viromer® so efficient?

Watch Our Video

Take two minutes to discover the story behind the Viromer® transfection reagents. Inspired by the machinery of the Influenza virus to penetrate cells and actively escape from the endosome, at Lipocalyx, we have been using this as a blueprint to develop a functional copy of the virus based on high-tech polymers.

The 4 color-named Viromer® and related customized reagents are the result of this work. This palette permits to provide the most appropriate chemistry to deliver RNA or DNA in each specific cell line you commonly use in research labs. And the story goes on with in vivo applications…

What is transfection?

Transfection is a Challenge

Transfection is a powerful method to introduce foreign DNA or RNA into eukaryotic cells. Delivery of nucleic acids into cells enables exploration of gene function and regulation, analysis of cellular pathways and signal transduction in cells, tissues and organisms.

There are various transfection techniques developed: viral transduction, mechanical methods (such as electroporation or microinjection), chemical methods (such as calcium phosphate, polymers or lipofection) and hybrid methods (such as magnetofection). Nevertheless, a successful transfection of certain cells remains a challenging task.
