1. What is DOTAP Chloride?

DOTAP Chloride, also known as 1,2-dioleoyl-3-trimethylammonium-propane chloride salt, is a cationic lipid widely used in the field of gene and drug delivery. As a synthetic amphiphilic lipid, DOTAP forms liposomes, which are vesicles composed of lipid bilayers. These vesicles facilitate the delivery of various molecules, such as nucleic acids, proteins, and other therapeutic agents, into target cells.

2. Types of DOTAP Chloride

Although DOTAP chloride is a specific lipid chemical compound, it can be combined with other lipids to create various types of liposomes. These liposome formulations can be categorized into:

• Multilamellar vesicles (MLVs): Large vesicles containing multiple lipid bilayers that can encapsulate a higher payload compared to other types.

• Small unilamellar vesicles (SUVs): Smaller vesicles with a single lipid bilayer, providing improved stability and control over the contained materials.

• Large unilamellar vesicles (LUVs): Like SUVs, these vesicles also have a single bilayer, but with larger diameters and lower surface-to-volume ratios.

3. Applications of DOTAP Chloride

DOTAP Chloride is primarily used in gene and drug delivery due to its ability to form liposomes and facilitate intracellular transport. Notable applications include:

Gene therapy: The delivery of therapeutic genes into target cells for disease treatment or prevention.

SiRNA delivery: The transport of small interfering RNA (siRNA) molecules into cells to knock down specific target genes.

Drug delivery: The encapsulation and targeted delivery of various drugs to enhance their efficacy and reduce off-target effects.

Vaccine development: Using liposomal carriers to improve antigens' immunogenicity and stability for effective vaccination.

4. Advantages of DOTAP Chloride

DOTAP Chloride offers various advantages over other types of lipids and delivery systems:

• High transfection efficiency: Provides efficient gene and drug delivery into target cells.

• Biocompatibility: Due to its low cytotoxicity, it is well-tolerated by cells and tissues.

• Flexibility: Can be combined with other lipids to create custom liposomal formulations targeting specific cells or tissues.

• Stability: Delivers improved stability and storage potential compared to other lipids.

5. Production of DOTAP Chloride

The production of DOTAP Chloride involves multiple stages, including:

• Synthesis: Chemical synthesis of the lipid using fatty acids and other building blocks.

• Purification: Removal of any impurities, such as colorants, solvents, or undesired byproducts, through different chromatographic techniques.

• Characterization: Assessment of the lipid’s physical, chemical, and functional properties to ensure its quality.

• Formulation: The creation of liposomes with DOTAP Chloride, along with other lipids and materials, according to specific application requirements.

6. Factors Affecting DOTAP Chloride Price

Several factors can influence the price of DOTAP Chloride:

• Production cost: The overall cost of raw materials, labor, and equipment required for synthesis.

• Purity levels: Higher purity grades often come with higher prices.

• Market demand: Fluctuations in demand for gene and drug delivery compounds can cause price fluctuations.

• Regulatory landscape: Compliance with regulations and standards may affect production costs and availability.

7. What to Pay Attention to When Buying DOTAP Chloride
