UBIQUANT S ALPHALISA

 

LifeSensors’ UbiQuant S AlphaLISA combines TUBEs (Tandem Ubiquitin Binding Entities) with cutting edge AlphaLISA technology to create a high throughput assay which enables researchers to measure the relative amount of polyubiquitylated proteins within a cell lysate.

Conceptual schematic of the UbiQuant S AlphaLISA assay. TUBEs conjugated to AlphaLISA donor beads bind to polyubiquitylated proteins from a cell lysate. Simulataneously, POI antibodies conjugated to AlphaLISA acceptor beads bind to the POI in the cell lysate. If ubiquitylated POI is present, the concurrent binding of antibody and TUBE brings the AlphaLISA donor and acceptor beads into close proximity, resulting in a luminescent signal that is quantitatively correlated to the level of ubiquitlyated POI.


Sample data from UbiQuant S ELISA and AlphaLISA assays. Jurkat cells were treated with bortezomib (BTZ) or BTZ in combination with selective USP7 inhibitor P0217564 (564). Following treatment and cell lysis, Ubiquitylation of USP7 was measured by the UbiQuant S ELISA and AlphaLISA assays.
