Microspheres
Polysciences, Inc. Polybead Microspheres 90.00um, 5ml
Polybead Microspheres 90.00m, 5mlPolybead Microspheres are monodisperse polystyrene microspheres available in sizes from 50nm to 90m. Diameters 4.5m and larger are crosslinked with divinylbenzene (DVB). Our experienced chemists control the synthesis to provide precise monodisperse particle size distributions. These particles contain a slight anionic charge from sulfate ester.Most Polybead Microspheres are packaged in an economical 2.5% solids (w/v) aqueous suspension with minimal surfactant in the final preparation. Polybead Microspheres are ideally suited for protein binding using passive adsorption techniques.

LifeSensors Tandem Ubiquitin Binding Entities (TUBE1) Magnetic 1mL
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.
