Mca-KKVAPYPME-Dap(Dnp)–NH2 | proteasome activity assay reagent

Mca-KKVAPYPME-Dap(Dnp)–NH2 | proteasome activity assay reagent

details

UbiQ-141, LF2 peptide assay reagent is a long fluorogenic reagent for monitoring ATP dependant protease activity like in the 26S proteasome and ClpP protease. [Jastrab et al.] Because the LF2 peptide is larger than standard tri/tetra peptide based assay reagents, LF2 is not processed by the 20S CP alone and activating factors are required.

 

UbiQ-141 | Key Characteristics

  • only processed by activated proteasomes [Jastrab et al.]
  • exhibits a much more pronounced stimulation of proteasome activity than tetrapeptide based proteasome activity assay reagents [Jastrab et al.]

  • processed by human and bacterial proteasomes
