Creative Biolabs is always dedicated to assisting our clients with the most satisfactory mRNA delivery-related solutions. Now, we are proud to offer a series of reagents for mRNA delivery, such as cationic lipids, to meet your requirement.
Recent drug-delivery approaches employ positively charged microparticles to deliver negatively charged macromolecular therapeutics such as DNA, oligonucleotides, and proteins. Cationic lipids are amphiphilic molecules, implying that they consist of a hydrophilic and a hydrophobic region, i.e., a (charged) cationic (amine) headgroup, attached via a linker (glycerol) to a double hydrocarbon chain or a cholesterol derivative, respectively. So far, cationic lipids as a component for gene delivery vehicles have become a powerful research tool for transferring exogenous genetic material into host cells.
An ideal cationic lipid for gene delivery should be efficient and non-toxic, forming highly stable particles with genes and facilitating the nuclear localization of genes. SA is a cationic lipid with surface-active properties commonly used to produce positively charged liposomes or emulsions. It has been applied to induce a positive charge in the liposomal bilayers and successfully form a potential gene transfer vehicle.
For example, SA and cholesterol (Chol) at equimolar ratio form stable large unilamellar vesicles with a high positive charge and limited permeability. Compared to other cationic liposomes, the transfer vehicle formulated with SA and Chol could be a better candidate for gene delivery due to their higher positive surface charge and significantly increased particle stability. They show some excellent advantages: (1) both components are small molecules, which are much easier to obtain and purify compared to macromolecules (e.g., polymers); (2) it would be easy for this system to scale up to meet the industry requirements.
