Ordering Information

Biological Activity

MZ-1 is a VHL-recruiting proteolysis targeting chimera (PROTAC) degrader of bromodomain-containing protein 4 (BRD4) that selectively targets BET bromodomains. By tethering BRD4 to the von Hippel-Lindau (VHL) E3 ubiquitin ligase, MZ-1 induces ubiquitin-dependent proteasomal degradation of BRD4. This depletion inhibits downstream BET-mediated transcriptional networks, downregulating oncogenic signaling pathways and suppressing cancer cell proliferation. [1]

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
