General description

Cationic liposomes are traditionally used for the delivery of genetic materials such as various types of DNA (pDNA, cDNA, CpG DNA, oligonucleotide, antisense oligonucleotide), various types of RNA such as (siRNA, mRNA) and nucleic acid mimics (NAMs). The positive, cationic charge of the lipids is used to neutralize the negative charge of nucleic acids and results in greater encapsulation efficiency, cellular uptake and endosomal delivery.

Application

Drug delivery
Gene delivery
Lipid-protein interactions

Storage and Stability

Liposomes should never be frozen. Liposomes should be stored in the dark at 4°C, except when brought to room temperature for brief periods prior to use.

Liposomes are made under sterile conditions. If you need to take multiple aliquots out of the vial, it is advised to take extreme care in not contaminating the vial. It is recommended to handle the vial under a sterile hood to maintain the sterility of the product. Liposomes should never be frozen. Ice crystals that form during freezing will rupture the lipid membrane of the liposomes and change the size of liposomes particles.

Approaches to the design of lipid-based nanocarriers

LNPs are ideal carriers for mRNA drugs, as evident from the two FDA-approved SARS-CoV-2 vaccines. However, efficient LNPs need further research on ionizable lipid selection, formulation, and administration. This review examines lipid usage, ionizable lipid selection, and LNP design for mRNA drug delivery.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
