Product Details

Biological Activity

DC 271 is a fluorescent retinoic acid analog (retinoid all-trans-retinoic acid; ATRA) (Kd = 42 nM at cellular retinoid binding protein II (CRABPII)). Solvochromatic probe: fluorescent λex, λem, and quantum yield affected by solvent type. DC 271 can be used in retinoids assays. Activates same genes as endogenous retinoic acid in human keratinocyte cells (HaCaT) when incubated for 72 h at 1 μM. Also elicits cellular responses consistent with those of retinoic acid. Excitation λ = 351, 350, 382 and 378 nm in DMSO, EtOH, DCM and Toluene, respectively; emission λ = 442, 461, 572 and 447 nm in DMSO, EtOH, DCM and Toluene, respectively. Quantum yield = 19.3, 1.14, 71.45, 80.21 % in DMSO, EtOH, DCM and Toluene, respectively.
