Turn your protein into exosome cargo with XPack™

Whether you’re engineering exosomes as protein delivery vehicles, labeling exosomes with a custom reporter protein, or performing functional studies, XPack gives you the power to package your protein-of-interest into exosomes.

XPack MSCV-XP-MCS-EF1α-Puro Cloning Lentivector

With the XPack MSCV-XP-MCS-EF1α-Puro Cloning Lentivector, you can use SBI’s well-proven lentivector technology to express your protein-of-interest and package it into exosomes. The strong MSCV promoter delivers high expression levels in hematopoietic and stem cell lines and the multiple cloning site downstream of the XPack tag enables fusion of the exosome-targeting peptide to your protein-of-interest (also available with a CMV promoter for expression in hematopoietic and stem cells).

The XPack System at a glance:

• Powerful—enables a wealth of applications, including
  • Exosome labeling
  • Exosome cargo tracking
  • Exosomes as cargo delivery vehicles
  • Exosomes as biotherapeutics
  • Exosome-generating stable cell lines with protein cargo-of-interest
• Optimized—SBI developed the XPack peptide tag for robust exosome targeting
• Reliable—based on SBI’s highly-cited, well-proven lentivector technology
• Versatile
  • Two promoter options for expression in a wide range of cells
  • Comes as pre-built reporters (GFP, RFP, luciferase) or ready-to-customize cloning lentivectors
