LifeSensors Tandem Ubiquitin Binding Entities (TUBE1) Magnetic 1mL
Supplier: LifeSensors UM0401M1000
Tandem Ubiquitin Binding Entities (TUBEs) have been developed for the isolation and identification of ubiquitylated proteins. TUBEs display up to a 1000-fold increase in affinity for polyubiquitin moieties over the single ubiquitin binding associated domain (UBA). In addition, TUBEs protect polyubiquitinated proteins from deubiquitination and proteasomal degradation, allowing for detection at relatively low abundance. These properties effectively allow TUBEs to “capture” protein in its polyubiqutinated state. TUBEs can be used to isolate, enrich, and identify ubiquitinated proteins from cell and tissue extracts. Magnetic beads coupled to TUBE 1 allow for efficient recovery of polyubiquitinated proteins in a single step without centrifuge. The magnetic TUBEs allows more complete removal of the unbound supernatant, which leads to lower background. Polyubiquitinated proteins can easily be separated from TUBEs for proteomic studies or identification by Western blotting.
