UbiQ-L02 is a panel of 10 deubiquitinating enzyme (DUB) activity-based probes (ABPs, 10 micrograms each).

UbiQ-L04 contains seven deubiquitylating enzymes (DUB) activity-based probes based on K6, 11, 27, 29, 33, 48, and 63 linked diUb.

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

UbiQ-158 is an activity-based probe for E1 activating enzymes and E2 conjugating enzymes that are involved in autophagy (e.g. ATG7 and ATG3, respectively). The N-terminus is labeled with an His6 affinity tag and a 3C protease cleavage site (QG), Cys17 has been mutated to a Ser residue (S).

Ubiquitin-Viny Sulfone is an inhibitor of deubiquitylating enzymes (DUBs).

His10-SUMO3-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 Here Lys63 has been replaced by a diaminobutyric acid residue equipped with a VME type warhead3.

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-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.

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

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

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

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 equipped with the propargyl amide (PA) electrophile and the isopeptide bond between the two Ub proteins is replaced by a DUB resistant mimic.

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

UbiQ-057 (Ub-PA) is an activity-based probe for deubiquitinating enzymes (DUBs) and contains propargyl amide (PA) as an electrophile.
