LightOx™21

≥95% (HPLC)
Retinoic Acid Analogue

Biochemical/Physiological Actions

Strong ligand for retinoic acid receptor proteins

Applications

• Fluorescence microscopy
• fluorescent retinoid binding assay
• fluorescence spectroscopy

Features and Benefits

LightOx™21 is a synthetic analogue of all-trans-retinoic acid (ATRA), that exhibits solvatochromatic fluorescence emission when excited with UV or 405 nm light. The compound is a strong ligand for the retinoic acid receptor proteins (RARs) and related cellular retinoic acid binding proteins (CRABPI/II) and can, therefore, be used as a replacement for ATRA in cellular assays involving retinoid signalling processes.

LightOx™21 can be utilised to study retinoid behaviour using fluorescence microscopy, employed in a competitive fluorometric ligand-binding assay for direct determination of the strength of binding of non-fluorescent retinoids to a protein target, and as a fluorophore in fluorescence spectroscopy.
