Anti-ubiquitin-HRP antibody is a pan-ubiquitin, mouse monoclonal antibody conjugated with HRP that is part of the Signal-Seeker™ product line. The antibody was raised against full length bovine ubiquitin.  The antibody has been shown to recognize poly-ubiquitin, mono-ubiquitin, and free ubiquitin (Fig 1). Ubiquitin is a highly conserved protein and AUB01 is predicted to recognize ubiquitin from a wide range of species (5). AUB01-HRP has been validated in western blot applications and has been shown to be more potent than unconjugated AUB01 used with standard mouse-HRP secondary.  AUB01 is purified by Protein G affinity chromatography and is supplied as a lyophilized white powder.



Ubiquitin Background

Ubiquitin (Ub) and ubiquitin-like proteins (Ubls, e.g. SUMO, Nedd) are a group of approximately 15 proteins that have a molecular weight of around 8 kD. During the ubiquitination process, these are conjugated via activating (E1), conjugating (E2) and ligating (E3) enzymes to lysines of a target protein (1). Mammalian cells express over 600 potential ubiquitin ligases which exceeds that of the kinase superfamily of PTM proteins (2).

One function of ubiquitination is to target proteins for proteosomal degradation. This role can range from a general housekeeping function that clears miss folded proteins from a cell to involvement in tightly regulated spatio-temporal cell signaling events (1). An emerging function of ubiquitination is its ability to activate proteins via the creation of unique protein:protein interactions (3). In common with many other PTMs, ubiquitination is reversible.  Ubiquitin-specific proteases (USPs or DUBs) remove ubiquitins from target proteins (4).  The reversible nature of ubiquitination further enhances the potential of this PTM to dynamically regulate protein function.
