Overview

Overview

Putting exosomes to work: Target exosomes to breast cancer cells Use exosomes to deliver protein, RNA, DNA, or small molecule cargo to breast cancer cells with XStamp-HER2. The patented XStamp technology is an optimized, exosome surface display system that efficiently places protein sequences on exosomal surfaces. The XStamp-HER2 Lentivector fuses HER2 sequences to the XStamp tag, ensuring that exosomes display the HER2 peptide on their outer surface. Exosomes made from cells transfected or transduced with the XStamp-HER2 Lentivector will now be targeted to cells expressing breast cancer cells.
  • Display HER2 sequences on exosome surfaces
  • Target breast cancer cells
  • Create stable XStamp-HER2 cell lines
XStamp-HER2 places HER2 sequences on the surface of your exosomes, targeting them to breast cancer cells SBI also offers a selection of pre-built targeting XStamp Lentivectors, as well as a clone-your-own XStamp Cloning and Expression Vector:

How It Works

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.

XStamp-motilin targets exosomes to GI cells.

Figure 1. XStamp with motilin specifically targets exosomes to GI cells. Motilin is a 22-amino acid polypeptide hormone that binds to the motilin receptor, which is exclusively expressed in the intestine. XStamp with motilin can be used to target exosomes to GI cells. METHODS: The XStamp-Motilin construct (Cat.# XSTP720PA-1) was transfected into HEK293 cells and after 48 hours, the exosomes were isoalted using ExoQuick-TC. The next day, the XStamp-Motilin exosomes were Exo-Fected with a Texas-Red-labeled siRNA to monitor exosome docking and delivery. The transfected XStamp-Motilin exosomes were then added to MDA-MB-231 Breast Cancer Cells (motilin receptor negative) and to HT-29 Colon Cancer Cells (motilin receptor positive). The cells were imaged after 24 hours for uptake of the Texas-Red-labeled siRNA delivery from the XStamped exosomes. The HT-29 colon cancer cells that are motilin receptor positive took up the XStamp-Motilin exosomes at a much higher rate than the MDA-MB-231 Breast Cancer (motilin receptor negative) cells.
