Ubiquitin+1 has a carboxyl terminal amino acid sequence that differs from normal Ubiquitin. The different carboxyl terminal sequence appears to result from a frameshift in the Ubiquitin mRNA. The underlying mechanisms creating the mRNA frameshift are not clearly understood. The occurrence of the frameshift that generates Ubiquitin+1 is much more prevalent in patients with Alzheimers Disease or with Down Syndrome than in control individuals who are not afflicted with the disorders. The monoclonal anti-Ubiquitin+1 (Catalog # MAB703) and rabbit polyclonal anti-Ubiquitin+1 (Catalog # AF703) antibodies were raised against the Ubiquitin+1 carboxyl terminal sequence that differs from normal Ubiquitin and are therefore non-reactive with Ubiquitin. Monoclonal anti-Ubiquitin (Catalog # MAB701) detects both Ubiquitin and Ubiquitin+1 indicating that the epitope recognized by this antibody is contained in the portion of the proteins that are identical (1, 2).

Human Ubiquitin+1 ELISA Standard Curve
Recombinant Human Ubiquitin+1 (Catalog # 703-UB) was serially diluted and captured by Mouse Anti-Human Ubiquitin+1 Monoclonal Antibody (Catalog # MAB7031) coated on a Clear Polystyrene Microplate (Catalog # DY990). Mouse Anti-Human Ubiquitin+1 Biotinylated Monoclonal Antibody (Catalog # ) was incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998)Applications for Human Ubiquitin+1 Antibody (83456)
