K11-only Ubiquitin (human), (recombinant) (untagged)
Product Specification
MW: ~8.6 kDa
Source: Produced in E. coli.
UniProt ID: P0CG48
Formulation: Lyophilized.
Purity: ≥95% (SDS-PAGE) (SDS-PAGE)
Purity Detail: Purified by perchloric acid treatment of a soluble lysate, followed by gradient elution from a cation exchange column.
Appearance: White solid.
Application: For production of poly-ubiquitin chains via Lys11 only.
Long Term Storage: -20°C
Miscellaneous/General: Lys11-only ubiquitin contains only a single lysine at position 11, with all other lysines mutated to arginine. This mutation renders ubiquitin able to form multi-ubiquitin chains only via Lys11. The ability to form an active thioester at the C-terminus is preserved, allowing Lys11-only ubiquitin to be transferred to the lysines of substrate proteins. |
