Extracellular vesicles

Innovative solution for membrane proteins’ study.

Most eucaryotic cells have the physiological capacity to produce extracellular vesicles. They are made of a lipid bilayer comparable to a cytoplasmic membrane and contain membranes proteins.

NabGen Technology has developped an innovative tool for membrane proteins presentation at the surface of extracellular vesicles.

Thanks to the implementation of an optimised and fast protocol, the platform provides to the project leaders extracellular vesicles decorated with the protein of interest, ready to be used and for mutliple applications.

Vesicles presenting membrane proteins

Membrane proteins are targets of choice for therapeutic research and immunotherapy. The study of their structures and interactions with the ligands such as therapeutic antibodies is a key element in the characterization of new candidates for example.

NabGen Technology offers a tool for membrane proteins presentation at the surface of vesicles.

Eucaryotics cells are transfected with the gene of interest cloned in an expression vector. Vesicles, mesuring from 40 to 100 nm, are purified and analysed to check their decorating rate. They are then conditionned and sent to the project leader.

Stable solutions, close to « real » conditions

Some methods permit to purify membranes proteins by extracting them from the membranes in which they are embedded thanks to the use of detergents. Those detergents weaken their stability and often lead to their partial or even total inactivation. Membranes proteins embedded in the vesicles produced by NabGen Technology are very stable and can be stored for several months at 4°C. In addition, they don’t need the use of any detergents and therefore remain functional. Their use allows to mimick the biochemical complexity of a true biological membrane. Indeed, a lipid bilayer or viral envelopp can sometimes take specific conformations according to the steric hindrance which depends on the density and the way proteins gather.

Extracellular vesicles produce by NabGen Technology constitute a tool of choice to study membranes proteins and their interactions.
