reagents

Ub-VME (UbiQ-005) is a potent, irreversible and specific inhibitor of deubiquitinating enzymes (DUBs).

UbiQ-287 is a fluorescence polarization assay reagent for deISGylating enzymes which is based on a 5-carboxytetramethylrhodamine (TAMRA, exc 550 nm, emi 590 nm) modified Lys-Gly sequence that is linked to human ISG15 via a native isopeptide bond.

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

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

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

Nedd8-FP (UbiQ-019) is a fluorescence polarization assay reagent which is based on a 5-carboxytetramethylrhodamine (TAMRA) modified Lys-Gly sequence that is linked to Nedd8 via a native isopeptide bond with the lysine side-chain.

UbiQ-073 is a fluorescence polarization assay reagent for deISGylating enzymes which is based on a 5-carboxytetramethylrhodamine (TAMRA) modified Lys-Gly sequence that is linked to (mouse) ISG15 via a native isopeptide bond with the lysine side-chain.

Ac-ISG15prox-Rh110MP (UbiQ-127) is a quenched, fluorescent substrate for ISG15 proteases based on the proximal part of (mouse) ISG15 (aa 77-155).

SUMO1-FP (UbiQ-020) is a fluorescence polarization assay reagent for de-SUMOylating enzyme, based on a 5-carboxytetramethylrhodamine (TAMRA) modified Lys-Gly sequence that is linked to (6His tagged) SUMO-1 via a native isopeptide bond with the lysine side-chain.

SUMO2-FP (UbiQ-021) is a fluorescence polarization assay reagent for de-SUMOylating enzyme, based on a 5-carboxytetramethylrhodamine (TAMRA) modified Lys-Gly sequence that is linked to (6His tagged) SUMO-2 via a native isopeptide bond with the lysine side-chain.

Class II fluorescence polarization HTS reagent based on the cullin-1 (711-730) polypeptide
