Overview:
Putting exosomes to work: Target exosomes to neurons

Use exosomes to deliver protein, RNA, DNA, or small molecule cargo to neurons with XStamp-NCAM. The patented XStamp technology is an optimized, exosome surface display system that efficiently places protein sequences on exosomal surfaces. The XStamp-NCAM Lentivector fuses NCAM sequences to the XStamp tag, ensuring that exosomes display the NCAM homophilic binding domain on their outer surface. Exosomes made from cells transfected or transduced with the XStamp-NCAM Lentivector will now be targeted to NCAM-expressing cells.

How It Works:
Engineering exosomes with specific surface proteins


XStamp is based upon a C-terminal fusion of the C1C2 domain from the protein MFG-E8, which is targeted to the exosome surface. Protein sequences that are fused to the XStamp tag will efficiently display the protein ligand fusion on the surfaces of secreted exosomes.
