D-Luciferin K salt D-Luciferin K salt, (S)-4,5-Dihydro-2-(6-hydroxy-2-benzothiazolyl)-4-thiazolecarboxylic acid, potassium salt [CAS: 115144-35-9]
Item #: L226 -

Chemical Structure Product Description D-Luciferin is a firefly luciferase substrate. Its quantum efficiency is 0.88, which is 20 times that of Luminol. The reaction mechanism is shown below. First, Luciferin reacts with ATP by luciferase in the presence of magnesium ion, then it is oxidized to form dioxetane structure and emits yellow-green light. Luciferin-luciferase luminescence is used for ATP monitoring to determine cell viability and bacteria counting. It is also used for reporter gene...

POPOP POPOP, 1,4-Bis(5-phenyl-2-oxazolyl)benzene [CAS: 1806-34-4]
Item #: P009 -

Chemical Structure Introduction Organic compounds that coordinate metal ions into circular structures (chelate circles) are called chelating reagents. Most chelating reagents include oxygen, nitrogen, or sulfur atoms in their molecules. Chelate structures with five or six member rings form the most stable chelate circle. In chelating reactions of typical chelating reagents, such as ethylenediamine, acetylacetone, and oxine, several molecules are coordinated with one metal ion. Ethylenediamine...

WSC WSC, 1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide, hydrochloride [CAS: 25952-53-8]
Item #: W001 -

Chemical Structure Product Description of Calixarenes WSC is a water soluble carbodiimide. It is also soluble in alcohol, acetone, chloroform, dioxane, and DMF. WSC is used as a condensing agent for peptide syntheses. WSC and its urea form can be easily removed after the reaction due to their high water solubility. WSC, EDC, EDAC, EDCI, and ethyl-CDI are the same reagent. ...
