LifeSensors Tandem Ubiquitin Binding Entities (K63 TUBE) FLUORESCEIN 50µg
Supplier: LifeSensors UM0504F0050
Fluorescein-labeled (FLR) K63 TUBE binds K63-linked polyubiquitin with a 1000 to 10,000-fold preference for K63 over other linkage types and provides a sensitive and cost-effective tool for determining the abundance of K63-linked polyubiquitin in the cell, or identifying the linkage-type associated with a particular protein of interest. FLR-K63 TUBE consists of multiple ubiquitin interacting motifs separated by rigid linkers, presumably increasing its affinity to extended K63 polyUb chains. FLR- K63 TUBE is useful for detection and characterization of K63-linked polyubiquitylated proteins by ‘far Western’ blotting and in situ detection (histo- or cyto-chemical staining). FLR-K63 TUBE has one fluorescein molecule conjugated to a single, defined location within the protein.
