Cell-Penetrating USER Cassette

This biobrick contains an AsiSI/Nb.BSMI USER Cassette with a N-terminal nona-histine (R9) Cell-penetrating peptide which gives proteins inserted into the cassette the ability to pass through plasma membranes. In addition the USER Cassette carries a N-terminal hexa-histidine tag which allows for easy purification.

For our study we demonstrated that proteins inserted into the cassette can be purified, using the histidine-tag, and subsequently transferred into E. coli cells through the use of the R9 peptide.

In addition; previous studies have shown proteins associated with R9, either covalently or non-covalently, to be able to enter a variety of cell types (link!).
