HA-Ubiquitin-Propargylamide is a potent, irreversible, and specific inhibitor of deubiquitinating enzymes (DUBs) based on a C-terminal electrophilic Vinyl Sulfone group. It targets three of the four major DUB families: UCH (Ubiquitin c-terminal hydrolases), USP (Ubiquitin Specific Proteases), OTU (Ovarian Tumor Proteases), and MJD (Machado-Josephin domain proteases) while JAMM metalloproteases are not inhibited. HA-Ub-Propargylamide can be used for activity profiling experiments and using the HA-Tag conveniently for Immunoprecipitations in search for new or novel enzymes reacting with the c-terminal warhead.

This product consists of a full-length, mature ISG15 polypeptide (amino acids 2-157) recombinantly expressed in E.coli, conjugated on its c-terminus to a quenched Rhodamine110 dye. Hydrolysis of the conjugate results in fluorescence observable by excitation at 485nm and emission at 535nm, which substantially reduces the risk of autofluorescence of compounds in screenings (Hassapien et al., 2007). Typical working range is 50-500nM.

KTSAVLQ-Rhodamine110-y-Glu (Lys-Tyr-Ser- Ala-Val-Leu-Glu-Rh110-y-Glu) is a Rhodamine 110 labeled fluorogenic peptidyl substrate that can be hydrolyzed by 3CLpro (Mpro) SBB-DE0129 a Chemotrypsin like protease, cleaving between the glutamine and the Rhodamine110 fluorophore. Prior hydrolysis, the Rhodamine110 moiety is quenched resulting in a very low background.

Catalog number: SBB-PS0003, 50 μg

This product consists of a full-length, mature NEDD8 polypeptide recombinantly expressed in E.coli, conjugated on its c-terminus to a quenched Rhodamine110 dye. Once hydrolyzed the free rhodamine provides excellent utility for real time assessment of enzyme activity at excitation (485 nm) and emission (535 nm). Typical working range is 50-500nM.

This SUMO1 substrate is C-terminally derivatized with a Glycine-Rhodamine-110 (3,6-diamino-9-(2-carboxyphenyl)) fluorophore. The Gly-Rh110 remains quenched until the amide bond between the C-terminal glycine and the Gly-Rh110 compound is hydrolyzed. The efficiency of quenching combined with the powerful signal upon hydrolysis yields a reagent with unparalleled signal-to-background. SUMO1-Rh110 can be used to study the deSUMOylating activity of hydrolases SENP1 and SENP2, or other deSUMOylating enzymes. The substrate activity of SUMO1-Rhodamine110 was determined by measuring the SENP1 catalyzed release of unquenched Gly-Rh110. The Excitation and Emission of this substrate is 485nm and 535nm respectively. This protein was expressed in E.coli.

This SUMO2 substrate is C-terminally derivatized with a bis-Glycine-Rhodamine-110 fluorophore. The bis-Gly-Rh110 remains quenched until the amide bond between the C-terminal glycine and the rhodamine compound is hydrolyzed. The efficiency of quenching combined with the powerful signal upon hydrolysis yields an unparalleled signal-to-background. SUMO2-Rh110 can be used to study the deSUMOylating activity of hydrolases SENP1 And SENP2, among other deSUMOylating enzymes. The substrate activity of SUMO2-Rhodamine110 was determined by measuring the SENP1 catalyzed release of unquenched Gly-Rh-110. This protein was expressed in E.coli.
