E3 ubiquitin ligases are standards in most antibody catalogs. These proteins are essential to the process of ubiquitination, which is expressed in protein pathways throughout the body and is often linked to disease states. It is widely used as a biomarker, with ubiquitin antibodies being widely used to identify the protein accumulations (inclusion bodies) which occur in conditions such as Alzheimer’s, Parkinson’s and Huntington's disease.
