R&D Systems™ Human 20S Proteasome Protein

Description

Extensive quality control produces industry leading bioactivity and lot-to-lot consistency that instills confidence in results and ensures reproducibility. Applications: Enzyme Activity

The Human 20S Proteasome is able to degrade substrates in an ATP-independent manner. Reaction conditions will need to be optimized for each specific application. We recommend an initial Human 20S Proteasome concentration of 0.5-5 nM.
