SUMO1-Dha is a new and first of its kind activity based probe for the SUMO ligation pathway.

UbiQ-115 (Biotin-Ahx-K63 diUbiquitin VME) probe is a potent, irreversible and specific inhibitor of deubiquitylating enzymes (DUBs) based on K63 linked diUb. Here Lys63 has been replaced by a diaminobutyric acid residue equipped with a VME type warhead3.

UbiQ-154 is a new crosslinking reagent based on ubiquitin in which Leu73 is replaced by the photoreactive analog photoleucine (photoLeu).

UbiQ-262 is an activity-based probe for and inhibitor of ISG15 proteases.

Biotin-Ahx-SUMO2-Dha (Dha= dehydroalanine) is a new and first of its kind activity based probe for the SUMO ligation pathway. [

Biotin-Ahx-Ub-VS (UbiQ-188) is a potent and specific inhibitor of deubiquitinating enzymes (DUBs) based on a C-terminal electrophilic vinyl sulfone (VS) group.

Biotin-Ahx-SUMO2-VME is an activity-based probe for SUMO proteases.

HA-Ahx-Ahx-Ub-VPS (UbiQ-193) is an activity-based probe and inhibitor of DUBs.

SUMO2-Dha is a new and first of its kind activity based probe for the SUMO ligation pathway.

His10-SUMO3-Dha is a new and first of its kind activity based probe for the SUMO ligation pathway.

Ubiquitin-propargylamide is a newly developed potent and specific inhibitor of deubiquitylating enzymes (DUBs).

Potent, irreversible and specific inhibitor based on K63 linked diUb that targets the S2 pocket of deubiquitinating enzymes (DUBs). The C-terminus of the proximal Ub is equiped with the propargylamide (PA) electrophile and the isopeptide bond between the two Ub proteins is replaced by a DUB resistant mimic.

HA-Ahx-Ahx-Ub-VS (UbiQ-187) is a potent and specific inhibitor of deubiquitinating enzymes (DUBs) based on a C-terminal electrophilic vinyl sulfone (VS) group.

Biotin-ANP-Ub-PA (UbiQ-077) is a newly developed potent and specific inhibitor of deubiquitylating enzymes (DUBs). It is labeled on the N-terminus with biotin and contains the UV cleavable 3-amino-3-(2-nitrophenyl)propanoic acid (ANP) linker, allowing for UV mediated cleavage of the biotin tag.

His6-Ahx-Ahx-SUMO2-VPS (UbiQ-237) is an activity-based probe for SUMO proteases.
