Purity:≥95% (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 Notes:For production of poly-ubiquitin chains via Lys48 only.
Shipping:Shipped on Blue Ice
Long Term Storage:-20°C
Scientific Background:Lys48-only ubiquitin contains only a single lysine at position 48, with all other lysines mutated to arginine. This mutation renders ubiquitin able to form poly-ubiquitin chains only via Lys48. The ability to form an active thioester at the C-terminus is preserved, allowing Lys48-only ubiquitin to be transferred to the lysines of substrate proteins.
Regulatory Status:RUO - Research Use Only
