Lock and Key Biosciences GmbH

Spending too much time troubleshooting recombinant protein expression? You're not alone.
To boost your yields of soluble protein in E. coli, we have developed the ProteoShells.

How it works. The ProteoShells envelop your proteins, favoring folding, and preventing aggregation and toxic interactions. Keep them as a shield for downstream applications, or release your protein by protease cleavage.

Easy to use. Insert your gene in the PS plasmid and use our reagents to isolate the expressed ProteoShells without chromatographic steps.

We are by your side. Things don't work for you? We offer our assistance at every step of the process. No time to spend using the ProteoShell yourself? Contact us and we can create and test an expression plasmid for you.
