UbiQ-092 is a ubiquitin protein that is phosphorylated on Thr7. Phosphoproteomic studies have identified several phosphorylated sites in ubiquitin, among them pThr7.

UbiQ-113 is ubiquitin that is phosphorylated on Ser57.

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.

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).

UbiQ-178 consists of the ubiquitin protein (Ub) in which Lys33 has been mutated to a cysteine residue.

UbiQ-094 is ubiquitin that is phosphorylated on Ser57.

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

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-176 consists of the ubiquitin protein (Ub) in which Lys27 has been mutated to a cysteine residue.

UbiQ-091 is ubiquitin that is phosphorylated on Ser65, a ubiquitin variant which has been shown to activate Parkin E3 ligase mediated ubiquitination.

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

UbiQ-174 consists of the ubiquitin protein (Ub) in which Lys6 has been mutated to a cysteine residue.

UbiQ-180 consists of the ubiquitin protein (Ub) in which Lys63 has been mutated to a cysteine residue.

UbiQ-095 is ubiquitin that is phosphorylated on Tyr59.

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