Application

NanoFabTx™ Maleimide Lipid Mix is a ready-to-use nanoformulation lipid mixture for the synthesis of maleimide-functionalized liposomes. Maleimide is a stable and easy-to-handle moiety that rapidly and covalently conjugates thiol groups of cysteine residues in proteins or peptides. This lipid mix enables users to encapsulate a wide variety of small molecules for targeting and immunotherapy applications without the need for lengthy trial-and-error optimization.
This product includes a curated lyophilized lipid mixture containing rationally selected lipids in precise ratios that have been optimized to achieve a desired size range of liposomes. Step-by-step protocols for the synthesis of liposomes surface-functionalized with maleimide groups using extrusion and microfluidics are also included. The synthesized maleimide-functionalized liposomes enable facile conjugation of targeting groups like proteins, peptides, and other thiol-containing moieties onto the liposome surface for targeted drug delivery.

Features and Benefits

  • A ready-to-use nanoformulation lipid blend for the synthesis of maleimide-functionalized liposomes
  • Step-by-step protocols developed and tested by our formulation scientists
  • Flexible synthesis tool to create uniform and reproducible liposomes
  • Maleimide surface functionalization allows for targeting ligand and protein conjugation to enable targeted drug delivery
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).
