Description
Protein | Ubiquitin-ATTO647 |
Origin | human, recombinant |
Molecular mass | 9.4kDa |
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 andE3- 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-ATTO647 of 0.01-0.5mM. 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. Ubiquitin-ATTO647 (λex647nm,λem669nm). |
Conjugation ratio | This product is supplied with a degree of labelling (DOL) of ~ 1. |
