Ordering Information

Biological Activity

Bexarotene is a synthetic, highly selective agonist of retinoid X receptors (RXRα, RXRβ, and RXRγ). Upon binding to RXRs, it induces homodimerization or heterodimerization with other nuclear receptors, such as retinoic acid receptors, peroxisome proliferator-activated receptors, and vitamin D receptors. This conformational activation modulates gene transcription pathways governing cellular differentiation, cell cycle arrest, and apoptosis in preclinical tumor models. [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).
