Origin

human, recombinant

Molecular mass

9.2kDa

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 of 0.01-0.5mM. 

ATTO488-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.

Ubiquitin-ATTO488 (λex 501nm,λem 523nm).
