GL-67 Liposomes for DNA/RNA Delivery

Online Inquiry

GL-67 liposomes are cationic liposomes specifically designed to deliver nucleic acids into cells via electrostatic interactions. As GL-67 liposomes are positively charged, they can interact with negatively charged nucleic acids. As a result, the liposomes form stable complexes with the nucleic acids, preventing them from degrading and enhancing their entry into the cell. A wide range of drug development and research applications can be supported with BOC Sciences' GL-67 liposomes for DNA/RNA delivery.

What is GL-67?

A GL-67 compound (N4-Spermine cholesteryl carbamate) consists of spermine, cholesterol, and carbamate groups. Due to its hydrophobic cholesterol portion, it is able to form a stable liposome that can fuse with the cell membrane, thus enabling the delivery of nucleic acids. With this carrier, the efficiency and specificity of delivery can be altered by adjusting its chemical structure to make it more biocompatible and biodegradable.

Features of GL-67 Liposomes

Efficient Gene Delivery

GL-67 Liposomes are capable of efficiently delivering DNA loads to target cells and enabling the expression of target genes within the cells.

Biocompatibility

As the main component is natural phospholipids, GL-67 liposomes have better biocompatibility and reduce adverse reactions to the organism.

Regulatability

The composition of GL-67 liposomes can be adjusted and optimized to improve gene delivery efficiency and specificity.

Long-term Stability

GL-67 Liposomes are able to maintain long-term stability under appropriate storage conditions, ensuring the quality and activity of the gene drug.

Design of GL-67 Liposomes

In order to design suitable cationic liposomes for DNA/RNA delivery, one should consider:

i) The ability to bind and package DNA/RNA in liposomes.

ii) The interaction of the packaged DNA/RNA with the cell surface.

iii) Efficiency of DNA/RNA internalization.

iv) Intracellular DNA/RNA release from endosomes in the presence of endocytosis involvement.

v) The level of transgene expression in pH-sensitive liposomes is based on their tendency to release their contents under acidic conditions.

The effectiveness of the interaction between liposomes and cells is highly dependent on liposome composition. Liposomes are captured by various endocytosis processes, the efficiency of which depends on cell type and liposome size. Liposomes of various sizes and charges can attach to macrophages and neutrophils by active phagocytosis.

Applications of GL-67 Liposomes

GL-67 liposomes have been shown to efficiently deliver DNA and RNA molecules to a variety of cell types, including cancer cells and immune cells. They are also used in gene therapy research to deliver therapeutic genes to treat diseases such as cystic fibrosis and muscular dystrophy.
