Label exosomes with luciferase using XPack™

Easily create stable cell lines that produce luciferase-labeled exosomes with the XPack MSCV-XP-Luciferase-EF1α-Puro Expression Lentivector. Take advantage of SBI’s well-proven lentivector technology to express luciferase from the strong MSCV promoter (also available with a CMV promoter for expression in hematopoietic and stem cells) and the optimized XPack exosome targeting tag to package luciferase into exosomes.

How It Works

How It Works

Optimized for success

With XPack, SBI has developed an optimized N-terminal peptide sequence that targets the peptide—and any protein fused to it—to the inner surface of the exosome membrane. Our pre-built XPack-reporter constructs come in GFP, RFP, and luciferase options to cover a wide range of labeling needs.

XPack efficiently packages luciferase into exosomes which can be used to deliver GFP to target cells

Part 1: Packaging luciferase into exosomes with XPack

The XPack-Luciferase fusion protein is efficiently packaged as exosome cargo and delivered to target cells. HEK-293 cells were transfected with a plasmid encoding an N-terminal XPack-Luciferase fusion protein (Cat.# XPAK532PA-1). Forty-eight hours later, exosomes were isolated using ExoQuick-TC® and luciferase levels quantified and compared to exosomes isolated from untransfected cells (Figure 1). Only XPack-Luciferase exosomes show robust luminescence indicating efficient packaging of luciferase into exosomes.

Part 2: XPack-Luciferase Exosome Delivery to Target Cells

The XPack-Luciferase exosomes isolated as described above were then added to recipient HEK-293 cells to test for luciferase delivery. After 24-hours, robust luminescence from cells exposed to XPack-Luciferase exosomes shows delivery of the luciferase cargo to the target cells (Figure 2). In contrast, untreated cells or cells treated with exosomes from untransfected cells show no luminescence.XPack-Luciferase exosomes deliver luciferase to target cells
