CAS No.: 116-31-4
All-trans-retinal is an vitamin A metabolite in the retina, and is produced following photo-isomerization of the visual chromophore 11-cis-Retinal. All-trans-retinal is cleared from photoreceptors by ATP-binding cassette transporter (ABCA4) and all-trans-retinol dehydrogenase (RDH). All-trans-retinal induces Bax activation via DNA damage to mediate retinal cell apoptosis .

CAS No.: 146368-16-3
Synonyms: Sulfo-Cy3 NHS ester; Sulfo Cyanine3 NHS ester
Cy3-SE (Sulfo-Cy3 NHS ester; Sulfo Cyanine3 NHS ester) is a sulfonated cyanine dye-derived fluorescent labeling reagent with λex of about 515 nm and λem of about 568 nm. Cy3-SE can interact with the π-π stacking of biomolecules (e.g., nucleoside monophosphates, proteins), inhibiting the photoisomerization process and increasing the fluorescence quantum yield and lifetime .

Synonyms: YOYO 1; YOYO1
Thiazole orange dimer YOYO 1 (YOYO 1) is a cell-impermeable cyanine dimer with no inherent fluorescence, and its fluorescence intensity increases significantly upon binding to double-stranded DNA (dsDNA) . Thiazole orange dimer YOYO 1 can serve as a nuclear counterstain or a dead cell indicator (Ex/Em = 505/512 nm).

Bis-Q is an acetylcholine (ACh) agonist that targets voltage-clamped muscle fibers of the fish Xenomystus nigris. Bis-Q exists in two forms: cis-Bis-Q (non-agonist) and trans-Bis-Q (agonist). Photoisomerization converts cis-Bis-Q to trans-Bis-Q, which induces agonist-induced currents. Channels activated by trans-Bis-Q and ACh have similar conductances and open times. Flashes increase the ratio of trans-Bis-Q to cis-Bis-Q until light equilibrium is reached. Further flashes transiently increase agonist-induced currents, indicating binding of trans-Bis-Q to desensitized receptors. Higher concentrations of cis-Bis-Q produce larger agonist-induced currents that decay exponentially. .

Previtamin D2 is a precursor to Vitamin D2 (ergocalciferol) , formed through the photoisomerization of ergosterol, a compound found in fungi and some plants. Exposure to ultraviolet (UV) light triggers the conversion of ergosterol to previtamin D2, which then rapidly isomerizes to vitamin D2.
