How to use

In Vitro:

The VHL protein is a substrate recognition subunit of two ubiquitously expressed and biologically important Cullin RING E3 ubiquitin ligase complexes. VHL is one of the most popular E3 ligases being recruited by bifunctional PROTACs to induce ubiquitination and subsequent proteasomal degradation of a target protein.
