ubpbio/Bovine 19S (PA700)/A1300/25 µg

来自 : 发布时间：2025-06-14

The 19S regulatory particle (PA700) locates on either one or both ends of the 20S core particle of the 26S proteasome. It has 19 subunits including six AAA ATPases that associate with α subunits of the 20S proteasome to form the 26S proteasome. PA700 plays an essential role in preparing substrate proteins to be degraded by the 20S proteasome, including binding, deubiquitinating and unfolding polyubiquitinated proteins.

Coomassie-stained SDS-PAGELane 1: Molecular weight markersLane 2: 5 µg purified Bovine 19S (PA700)

Coomassie-stained native-PAGELane 1: 5 µg purified Bovine 19S (PA700)

Activation of 5 nM 20S proteasome (Cat. # A1400) by 25 nM PA700, the proteasome activity was assayed by using 50 µM Suc-LLVY-AMC (Cat. # G1100) as the substrate. The AMC fluorescence was monitored by a plate reader with excitation and emission filters of 360±40 nm and 460±30 nm, respectively.
