d luciferin 6′ methyl ether

D-Luciferin 6'-methyl ether sodium salt functions as an inhibitor of firefly luciferase and acts as a cofactor in the Luc-catalyzed synthesis of dinucleoside polyphosphates [1] [2].

D-Luciferin potassium (D-Luciferin K Salt) is a popular bioluminescent substrate of luciferase in the presence of ATP.

D-Luciferin Sodium is a heterocyclic light-emitting compound and natural ligand for luciferase used to detect cell activity. The salt form of luciferin dissolves in water or other typical buffers.

4-Methylumbelliferyl β-D-Galactopyranoside-6-sulfate (sodium salt) (4-MU-Gal-6S) is a fluorogenic substrate used to quantify N-acetylgalactosamine-6-sulphatase (GALNS) activity. 4-MU-Gal-6S is cleaved by GALNS to release the fluorescent moiety 4-MU. 4-MU fluorescence is pH-dependent with excitation maxima of 320 and 360 nm at low (1.97-6.72) and high (7.12-10.3) pH, respectively, and an emission maximum ranging from 445 to 455 nM, increasing as pH decreases. It has been used to detect Morquio disease type A, a lysosomal storage disorder in which GALNS is deficient. 4-MU-Gal-6S can be used to assess GALNS activity in a very small blood volume to determine the extent of deficiency.

6-Chloro-3-indoxyl-α-D-mannopyranoside serves as a chromogenic substrate for the enzyme α-mannosidase, generating a salmon-colored precipitate upon enzymatic cleavage.

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.

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

3-Methyl-8-(2'-deoxy-β-D-ribofuranosyl)isoxanthopterin is a pteridine-based fluorescent guanosine analogue and DNA uptake tracer, extensively utilized for investigating DNA binding and dynamics, with an absorbance peak at 350 nm and an emission peak at 430 nm [1].
