Biological Activity

Description

Aurora-A ligand 2 is a ligand for the target protein of PROTAC. Aurora-A ligand 2 can be used to synthesize SK4454 (HY-179640)^[1].

IC₅₀ & Target^[1]

Aurora A

All Aurora Kinase Isoforms :

In Vitro

PROTACs contain two different ligands connected by a linker; one is a ligand for an E3 ubiquitin ligase and the other is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins.

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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.
