Biotin-Ahx-SUMO2-Dha (Dha= dehydroalanine) 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 equiped with the propargylamide (PA) electrophile and the isopeptide bond between the two Ub proteins is replaced by a DUB resistant mimic.

SUMO1-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.

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

UbiQ-179 consists of the ubiquitin protein (Ub) in which Lys48 has been mutated to a cysteine residue.

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

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

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 Here Lys63 has been replaced by a diaminobutyric acid residue equipped with a VME type warhead3.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-041 (K382 Ub-p53(368-389)-FP) is a class II fluorescence polarization HTS reagent based on the C-terminal peptide sequence 368 – 389 of p53, which contains various lysine residues that are (mono)ubiquitinated.

UbiQ-041 (K382 Ub-p53(368-389)-FP) is a class II fluorescence polarization HTS reagent based on the C-terminal peptide sequence 368 – 389 of p53, which contains various lysine residues that are (mono)ubiquitinated.

UbiQ-023 is a fluorescence polarization HTS control reagent that can be used to make a concentration calibration curve and determine the grating factor (G).

His10-SUMO3-Dha 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).

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