Protoporphyrin IX is a final intermediate in the heme biosynthetic pathway, which acts as a radiation sensitizer enhancing ROS generation even in a hypoxic state and inducing DNA damage. Protoporphyrin IX also acts as a photo sensitizer undergoing photobleaching that occurs through direct degradation by light irradiation. Protoporphyrin IX is formed and accumulated following 5-aminolevulinic acid (5-ALA) (HY-W000450) administration in the tumor cells of rats. Protoporphyrin IX causes selective improvement of basal cell carcinoma when activated red fluorescence of a peak wavelength at 405 nm. Protoporphyrin IX is promising for research of sonodynamic and photodynamic agents for a wide range of cancers, such as bladder cancer and nodular basal cell carcinoma .

Synonyms: EthD-1
Ethidium homodimer (EthD-1) is a high-affinity fluorescent nucleic acid dye commonly used to stain mammals, bacteria, yeast, and fungi. Ethidium homodimer binds to DNA or RNA, enhancing fluorescence more than 30 times. The Ethidium homodimer has a strong positive charge, so it cannot cross cell membranes and stain living cells; But the Ethidium homodimer can cross the disordered region of the dead cell membrane to reach the nucleus and embed the DNA double strand to produce red fluorescence. Therefore, Ethidium homodimer is a relatively sensitive nucleic acid stain that can accurately detect nucleic acids in solution or in decomposing cells. Ethidium homodimer binds DNA, Ex/Em=528/617 nm .

Dehydroergosterol is a fluorescent cholesterol analog (Ex/Em = 325/375 nm) used in cholesterol transport, membrane structure research, and live-cell imaging. Unlike cholesterol, Dehydroergosterol contains three additional double bonds, an extra methyl group, and an ergosterol side chain, forming a conjugated system that produces intrinsic fluorescence. In its monomeric form, Dehydroergosterol exhibits excitation peaks at 310-311, 324, and 338-340 nm, as well as emission peaks at 354, 371-375, 390-394, and 414 nm; in its microcrystalline form, Dehydroergosterol shows enhanced excimer emission around 404 and 426 nm. Dehydroergosterol mimics the properties of cholesterol, integrates into membranes and lipoproteins, and localizes to organelles .

CO probe 1 (probe 2) is a highly efficient fluorescent CO probe (Ex=493 nm) with an allyl ether reaction site. In the presence of PdCl₂, CO reduces Pd 2+ to Pd 0, triggering a Tsuji-Trost reaction that removes the allyl protecting group, releases fluorescein, and generates a significant fluorescence signal. CO probe 1 has high selectivity, rapid response (fluorescence enhancement of 150 times within 20 minutes), and low cytotoxicity, and can be used for real-time imaging of CO in living cells. CO probe 1 may be used to study pathological mechanisms involving CO signaling regulation, such as inflammation, vascular disease, or cancer .

Synonyms: Methacryloyloxy fluorescein
Fluorescein O-methacrylate (Methacryloyloxy fluorescein) is a pH-responsive fluorescent monomeric dye. Fluorescein O-methacrylate exhibits pH-responsive fluorescence properties: its fluorescence is activated under alkaline conditions and quenched under neutral or acidic conditions; reversible switching of fluorescence is achievable by adjusting the pH of the solution. Fluorescein O-methacrylate can be used as a monomer for the synthesis of amphiphilic fluorescein polymers. These polymers can self-assemble into stable polymer nanoparticles with enhanced aqueous-phase fluorescence, and also enable the conjugation of nanoparticles with amine-containing biomolecules to support sensitive optical detection of biomarkers (Ex/Em = 490/520 nm) .
