Figure 4From: Detection of ubiquityl-calmodulin conjugates with a novel high-molecular weight ubiquitylprotein-isopeptidase in rabbit tissues Sensitivity of anti-ubiquitin antibodies against free ubiquitin. Linear regression between the amount of monomeric unconjugated ubiquitin and the bandvolume specified in pixelintensity. The detection limit of monomeric ubiquitin is in a range of 0.1 to 1 μg linear. The detection limit of ubiquitin was 0.05 μg.Back to article page
