This Ubiquitin antibody was raised against purified bovine ubiquitin.


PBS, 30% glycerol and 0.035% sodium azide.


Ubiquitin antibody specifity
Dot blot analysis was used to confirm the specificity of Ubiquitin antibody. 50 ng, 10 ng, and 2 ng of either recombinant Ubiquitin (Lane 1) or BSA (Lane 2) were spotted onto nylon membrane and probed with Ubiquitin antibody at 2 µg/ml.


Ubiquitin is an important signaling protein that is catalytically added to proteins on lysine residues to modify their function. Addition of multiple ubiquitin proteins in a string (poly-ubiquitylation) to proteins signals their destruction by the proteasome. Mono-ubiquitylation of proteins has a much different effect, more in keeping with post-translational modification of proteins by phosphorylation or acetylation. Mono-ubiquitylation is part of a number of signal transduction pathways, including those involving histone proteins and transcriptional regulation.
