7methyl6thioguanosine

MESG, a chromophoric substrate, can be used to quantitate inorganic phosphate.

6-Ethyl-7-hydroxy-4-methylchromen-2-one is a fluorescent dye.

1-Methyl-7-nitroisatoic anhydride (1M7) is a reagent. It detects local nucleotide flexibility, for probing 2'-hydroxyl reactivity.

7-Hydroxy-4-methyl-2(1H)-quinolone (compound 2b), a fluorescent hydroxylated derivative, serves as a probe for detecting hydroxyl radicals associated with DNA damage [1]. It should be protected from light for preservation.

Sodium 2,2',2'',2'''-((((1,1-dioxido-3H-benzo[c][1,2]oxathiole-3,3-diyl)bis(6-hydroxy-5-isopropyl-2-methyl-3,1-phenylene))bis(methylene))bis(azanetriyl))tetraacetate is a useful organic compound for research related to life sciences. The catalog number is T65315 and the CAS number is 1945-77-3.

5(6)-Carboxy-2’,7’-dichlorofluorescein diacetate is an oxidant-sensitive and cell-permeable fluorescent probe.1Base hydrolysis of the ester bonds by intracellular esterases releases the acetate groups and the resulting compound, 5(6)-carboxy-2’,7’,-dichlorofluorescein, is oxidized by reactive oxygen species (ROS) and nitric oxide (NO) and displays excitation/emission maxima of 504 and 530 nm, respectively, which can be quantified as a measure of oxidant production. 1.Hempel, S.L., Buettner, G.R., O’Malley, Y.Q., et al.Dihydrofluorescein diacetate is superior for detecting intracellular oxidants: Comparison with 2’,7’-dichlorodihydrofluorescein diacetate, 5(and 6)-carboxy-2’,7’-dichlorodihydrofluorescein diacetate, and dihydrorhodamine 123Free Radic.
