Recombinant Human Tetra-Ub (K63-linked) Rhodamine 110, CF Summary

Product Specifications

Purity
>95%, by SDS-PAGE under reducing conditions and visualized by Colloidal Coomassie® Blue stain.
Activity
K63-linked tetra-Ubiquitin Rhodamine 110 is ideal for use in assays requiring fluorescent detection of deubiquitinase activity.  Optimal fluorescence at pH 8.0 is monitored with excitation and emission wavelengths of 485 nm and 535 nm, respectively.  Reaction conditions will need to optimized for each specific application.  We recommend an initial concentration of 0.1-1 μM.
Source
E. coli-derived human Tetra-Ubiquitin protein
Accession #
Predicted Molecular Mass
35 kDa

Carrier Free

What does CF mean?

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

What formulation is right for me?

In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: Tetra-Ubiquitin

Linkage specific poly-Ubiquitin chains may be used as a substrate for in vitro reactions with deubiquitinating enzymes ("DUB's") that cleave the peptide or isopeptide linkage between adjacent Ubiquitin molecules. K63-linked tetra-Ubiquitin chains are manufactured using recombinant wild-type human Ubiquitin and linkage-specific enzymes. The use of purely enzymatic techniques avoids the potential for contaminating synthetic intermediates. This fluorogenic substrate is intended for use with deubiquitinating enzymes that are unable to use mono-Ubiquitin-Rh110 (Catalog # U-555) as a substrate, or enzymes with activity that is stimulated by poly-Ubiquitin chains. The substrate consists of a K63-linked tetra-Ubiquitin chain with a single rhodamine attached to the C-terminus of the proximal Ubiquitin.
