HaloPROTAC 4

HaloPROTAC 4 is a HaloPROTAC degrader with a pIC₅₀ of 8.1 against human CRBN. HaloPROTAC 4 binds to CRBN to recruit the CUL4^CRBN E3 ubiquitin ligase complex, and covalently binds to HaloTag fusion proteins, thereby inducing proteasome-dependent degradation of HaloTag fusion proteins. HaloPROTAC 4 serves as a protein knockdown tool for chemogenetic-related studies.

Description

HaloPROTAC 4 is a HaloPROTAC degrader with a pIC₅₀ of 8.1 against human CRBN. HaloPROTAC 4 binds to CRBN to recruit the CUL4^CRBN E3 ubiquitin ligase complex, and covalently binds to HaloTag fusion proteins, thereby inducing proteasome-dependent degradation of HaloTag fusion proteins. HaloPROTAC 4 serves as a protein knockdown tool for chemogenetic-related studies^[1]. (Pink: Cereblon ligand (HY-187338); Blue: E3 ligase ligand; Black: linker).

All PROTACs Isoforms :

In Vitro

HaloPROTAC 4 (compound 15) binds to purified cereblon protein, with a mean pIC₅₀ of 8.1^[1].
HaloPROTAC 4 induces dose-dependent degradation of FAK-HaloTag-HiBiT in A549 cells, with a pDC₅₀ of 8.57 and a D_max of 59.5% after 24 h of incubation; in addition, the degradation of FAK-HaloTag-HiBiT depends on CRBN binding, HaloTag binding, cullin neddylation and proteasome activity^[1].
HaloPROTAC 4 induces dose-dependent degradation of endogenous MARC1-HaloTag-HiBiT and HiBiT-HaloTag-BRD4 in HEK293 cells, with a maximum degradation rate of approximately 80% after 24 h of incubation; in addition, the degradation of HiBiT-HaloTag-BRD4 shows concentration dependence^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
