VHL Ligand 8 is a VHL ligand. VHL Ligand 8 can be used to synthesize ARD-266 (HY-133020), a highly potent and VHL E3 ligase-based androgen receptor (AR) PROTAC degrader. ARD-266 effectively induces degradation of AR protein in AR-positive LNCaP, VCaP, and 22Rv1 prostate cancer cell lines with DC50 values of 0.2-1 nM.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
