Description

20S Proteasome activator 1 is a potent 20S proteasome activator with EC200 values of 0.3 μM, 0.7 μM and 1.8 μM for trypsin-like site, chymotrypsin-like site and caspase-like site. 20S Proteasome activator 1 translates well in a cellular system, preventing the accumulation of the pathogenic A53T mutant of α-synuclein. 20S Proteasome activator 1 can be used for researching neurodegenerative diseases[1].

IC50 & Target

IC50: 0.3 μM (trypsin-like site), 0.7 μM (chymotrypsin-like site), 1.8 μM (caspase-like site)[1]
In Vitro

20S Proteasome activator 1 (compound 19) (2.5-15 μM; 45 min) degrades 73% α-synuclein at 10 μM, and over 80% at 15 μM[1].
20S Proteasome activator 1 (5-15 μM; 24 h) reduces 25% A53T mutant, and dose-dependently reduces enhancement of α-synuclein in Hek-293T cells (transiently transfected with an A53T mutant α-synuclein plasmid) at 5 μM; decreases 67% A53T α-synuclein at 15 μM[1].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 2.5 mg/mL (5.07 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
