LifeSensors, Inc. is a biotechnology company leading the development of innovative research tools and services for the ubiquitin and ubiquitin-like protein pathways. Our unique capability is provide researchers with solutions along every aspect of the ubiquitin proteasome pathway – E3 ligases, DUB enzymes/assays/substrates, ubiquitin chains and mutants, inhibitors, ubiquitin isolation and detection reagents and kits to measure substrate ubiquitylation. Besides producing ubiquitin research tools, we also provide custom services to laboratories who demand substrate identification and purification for example E3, E3 substrate, DUB, or DUB substrate identification. In addition to our ubiquitin expertise, LifeSensors provides prokaryotic and eukaryotic protein expression platforms: SUMOpro and SUMOstar. Researchers may purchase the reagents for expression in their own lab or contract with us for customized protein expression services. Lastly, we also collaborate with research organizations in licensing our own proprietary products or in co-development of unique proteins that will serve researchers worldwide.
