Ordering Information

Biological Activity

Elacestrant Dihydrochloride is an orally bioavailable selective estrogen receptor degrader (SERD) that targets ERα and ERβ. By binding to estrogen receptors, it promotes target receptor degradation and suppresses estrogen receptor-mediated transcriptional activity. This downregulation disrupts downstream signaling pathways required for cell survival and proliferation, leading to the inhibition of growth in ER-positive breast cancer models and suppression of xenograft tumor growth.

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).
