D-Luciferin Potassium Salt 是一种萤光素酶的底物，能够催化生物发光昆虫产生典型的黄绿光。

D-Luciferin is a popular bioluminescent substrate of luciferase in the presence of ATP.

Enolase activity assay is in the 2.0 mM MgSO4 and 400 mM KCl in the absence or presence of ENOblock or NaF, at 37°C by incubating pure enolase (3–9 U) in a buffer containing 50 mM imidazole-HCl (pH 6.8). The reaction is initiated by adding 1 μmol of 2-phospho-D-glycerate, and the OD is measured after 10 min of reaction time with a spectrophometer at 240 nm.
