LifeSensors UbiTest Magnetic TUBE Elution Kit
Supplier: LifeSensors UM0411M1000
The UbiTest kit determines whether or not a target protein is poly-ubiquitinated. This powerful platform is an improvement on the most common method for investigating protein ubiquitination: immunoprecipitation and Western blot analysis. However, the substrate antibody often interacts differently with the poly-ubiquitinated forms of the substrate in the immuno-blotting step. This is due to epitope masking, reduced affinity, or changes in selectivity. A more definitive method for demonstrating protein ubiquitination is to couple immunoprecipitation with digestion by a broad spectrum deubiquitinase (DUB) prior to immunoblot analysis. An increased signal for the protein of interest (POI) after DUB treatment is a clear indication that the protein was ubiquitinated even if there was no clear reactivity in the untreated sample.
