enabling drug discovery in the ubiquitin field since 2010
Access to well-defined and advanced ubiquitin research tools and ubiquitin-like research tools is of paramount importance for drug development, fundamental research and structural studies. Since we founded our company in 2010, our ubiquitin and ubiquitin-like research tools have been well-recognised by both Pharma & Academia. Many leading laboratories in the field worldwide use our innovative and custom reagents. We also collaborate with outstanding scientists on research projects to further our insights in this growing field. We are proud that our joint efforts regularly result in publications in high-ranking journals. You can find examples in "our publications" section below this page. For an extensive list of our publications, please visit our resource download center.
Please explore how our ubiquitin research tools expedite the three stages of early drug discovery, i.e. target - lead - lead on target, by clicking on the buttons below:
target
Identify and validate your target using our probes
hit-to-lead
compound screening using our assay reagents
lead on target
lead on target validation and lead optimization
target
Identify and validate your target using UbiQ Probes.
lead
Screen your compounds targeting DUBs and Ubl proteases using UbiQ Assay reagents.
lead on target
Our reagents enable you in lead on target validation and lead optimization.
catalogue ubiquitin reagents
In our laboratory at the Amsterdam Science Park, UbiQ develops, manufactures, and commercializes research tools such as ubiquitinated peptides, activity-based probes, and activity assay reagents. In addition to ubiquitin, we also make ubiquitin-like variants (SUMO, ISG15, NEDD8, etc.) of our reagents.
Please note our research tools are “For laboratory research use only, not for use in animals and humans".
custom ubiquitin reagents
With our UbiQ technologies we can synthesize in a site-selective manner ubiquitinated peptides and reagents that are not readily available through biological approaches. Next to our catalogue reagents, we offer a tailored chemical approach to producing specific ubiquitinated conjugates. This custom ubiquitin synthesis approach allows researchers to design unique ubiquitinated peptides and ubiquitin reagents.
