Cationic Liposome Development Service

Cationic liposomes are one of the most extensively researched non-viral vectors for gene delivery due to their unique ability to interact with negatively charged DNA and cell membranes. Creative Biolabs provides cutting-edge cationic liposome development services tailored to various research and clinical needs. These services offer researchers advanced solutions in gene delivery systems, allowing for efficient transfection and delivery of therapeutic agents into targeted cells.

Strategy of Cationic Liposome Formulation

The formulation of cationic liposomes involves the selection of specific lipid components that provide a positive charge to the surface of liposomes. This positive charge allows the liposomes to form complexes with negatively charged DNA, RNA, or other molecules, facilitating efficient delivery into cells. The most commonly used cationic lipids include:

• DOTAP (1,2-dioleoyloxy-3-(trimethylammonium)propane)
• DOPE (1,2-Dioleoyl-sn-glycero-3-phosphoethanolamine)
• DOTMA (N-[1-(2,3-dioleoyloxy)propyl]-N,N,N-trimethylammonium chloride)

Cationic liposomes are prepared through a multi-step process, starting with the dissolution of lipids in organic solvents, followed by the formation of lipid films, hydration, and encapsulation of the desired payload. The formulation process ensures optimal lipid-to-nucleic acid ratios, promoting high transfection efficiency and stability.

Background of Liposome-Based Adjuvant

Cationic liposomes were first developed as a non-viral gene delivery method, offering a safer and more versatile alternative to viral vectors. Since their discovery, these liposomes have gained significant attention due to their unique ability to interact with negatively charged nucleic acids and cell membranes.

Cationic liposomes emerged in the 1960s when Alec D. Bangham discovered liposomes while studying lipid bilayers. In the 1980s, researchers like Philip Felgner introduced cationic lipids like DOTMA, which led to a revolution in gene transfection technologies. These liposomes are characterized by their positive surface charge, which allows them to bind with negatively charged DNA and RNA. Upon interacting with cell membranes, they facilitate the delivery of nucleic acids into cells via fusion or endocytosis, making them an ideal candidate for gene delivery research.
