General description

NanoFabTx-DOTAP Lipid Mix includes reagents and optimized protocols with step-by-step instructions for synthesizing cationic liposomes for drug delivery research applications. The modification of liposomes with the cationic lipid, DOTAP, have numerous advantages such as their large-DNA incorporation, high transfection efficiency, and low toxicity. Liposome-based formulations are widely used for drug delivery applications and enable improved therapeutic efficacy of a range of drug types including small molecules, nucleic acids, proteins, and peptides.

Comprehensive protocols for liposome synthesis are included:

  • A lipid film hydration and extrusion protocol.
  • A microfluidics protocol using commercial platforms or syringe pumps.

The microfluidics protocol included with this product uses NanoFabTx device kits (911593). These kits come with the microfluidics chips, fittings, and tubing required to get started with microfluidics-based synthesis (compatible microfluidics system or syringe pump required).

Application

NanoFabTx-DOTAP Lipid Mix is a ready-to-use nanoformulation blend for the synthesis of cationic DOTAP-functionalized liposomes. This kit enables users to encapsulate a wide variety of therapeutic drug molecules for targeted or extended drug delivery without the need for lengthy trial-and-error optimization. NanoFabTx kits provide an easy-to-use toolkit for encapsulating a variety of therapeutics in nanoparticles, microparticles, or liposomes. Drug encapsulated particles synthesized with the NanoFabTx kits are suitable for biomedical research applications such as oncology, immuno-oncology, gene delivery, and vaccine delivery.

Features and Benefits

  • A ready-to-use nanoformulation blend for the synthesis of cationic liposomes
  • Step-by-step protocols (extrusion or microfluidic) developed and tested by our formulation scientists
  • Flexible synthesis tools to create uniform and reproducible liposomes
  • Optimized to make liposomes around 100 nm with low polydispersity
  • DOTAP surface-functionalized allows for targeting ligand conjugation to enable targeted drug delivery
