Simple Western™ analysis of lysates (0.1 mg/mL) from U-937 cells using VHL Antibody #68547. The virtual lane view (left) shows the target band (as indicated) at 1:10 and 1:50 dilutions of primary antibody. The corresponding electropherogram view (right) plots chemiluminescence by molecular weight along the capillary at 1:10 (blue line) and 1:50 (green line) dilutions of primary antibody. This experiment was performed under reducing conditions on the Jess™ Simple Western instrument from ProteinSimple, a BioTechne brand, using the 2-40 kDa separation module.

Product Description

The PROTAC E3 Ligase Profiling Antibody Sampler Kit provides an economical means of detecting selected PROTAC E3 ligases. The kit includes enough antibodies to perform two western blot experiments with each primary antibody.

Background

PROTAC (proteolysis-targeting chimera) is a technique that uses a class of small molecules to target specific proteins for degradation (1). The small molecules are heterobifunctional, consisting of two protein binding parts joined by a linker. One part of the molecule binds a protein of interest (POI), while the other part binds to an E3 ubiquitin ligase, bringing the E3 ligase close to the POI for ubiquitination coupled protein degradation (2). The first successful PROTAC study used the chimeric PROTAC-1 molecule to recruit the β-TrCP E3 ligase to dictate the ubiquitination and degradation of MetAP2 (3). There are over 600 E3 ligases, and only a few have been successfully developed by PROTAC to degrade target proteins (4). Among them, CRBN- and VHL-based PROTAC have been extensively explored and successfully applied for multiple disease treatments (5,6). The E3 ligased MDM2, c-IAP, and XIAP are fruitful in using PROTAC strategy for cancer treatment (7-9). PROTAC design using the KEAP1 E3 ligase has been developed for degradation of BRD3, BRD4, and Tau. KEAP1 is another promising member of the PROTAC team (10,11).
