General description

NanoFabTx- PEG Lipid Mix; for synthesis of PEGylated liposomes is a ready-to-use nanoformulation lipid blend that includes lyophilized lipids and step-by-step instructions for synthesizing PEGylated liposomes for small molecule drug delivery applications. Lipid-based formulations are widely used for drug delivery and enable improved therapeutic efficacy of a range of drug types including small molecules, nucleic acids, proteins and peptides. PEGylated liposomes are capable of encapsulating both hydrophilic and lipophilic compounds and are an effective mechanism to increase the efficiency of drug delivery by prolonging the lifetime of the drug-encapsulated liposome.


NanoFabTx is a collection of ready-to-use drug formulation kits, lipid mixes, and microfluidic device kits for the synthesis of nanocarriers and microcarriers for drug delivery. The kits enable 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 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 lipid blend for the synthesis of PEGylated liposomes
  • Step-by-step protocols (extrusion and microfluidics) developed and tested by our formulation scientists
  • Flexible synthesis tool to create uniform and reproducible liposomes
  • Optimized to make liposomes around 100 nm with low polydispersity
  • Optimized lipid blend for stealth PEGylated liposomes for small molecule encapsulation
The NanoFabTx- PEG Lipid Mix provides reagents and protocols for extrusion and microfluidics to synthesize liposomes for drug delivery research application. This reagent kit can be combined with the NanoFabTx Microfluidic - nano device kit (Cat.No. 91153) for microfluidic synthesis of PEGylated liposomes.

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 the NanoFabTx device kit (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).
