Molecular mass




Protein description
















Ubiquitin is a ubiquitos regulatory protein (8.5kDa) that can be conjugated to substrate

proteins by subsequent actions of enzymes, such as:: E1 - class of Ubiquitin

activating enzymes, E2 - class of Ubiquitin  conjugating enzymes and E3- class of

Ubiquitin ligases, All assays have to be optimized for the individual set up and it is

recommended to start with initial concentration of Ubiquitin-Atto488/ Atto565/ Atto647

of 0.01-0.5mM.

Atto488/ Atto565/ Atto647-labeled ubiquitin is used as a general research tool or in

high throughput assays (HTS) to monitor protein ubiquitination. The labelling method

of the ubiquitin protein keeps all lysines functional for further and guarantees the full

function of the protein.
