描述：

D-Lucifern, also known asbetle ucifern or(D-)2-(6'hydroxy-2'benzothiazoly)-thiazoline-4carboxylic aid), has formula weight of

318.41 and isa yntheicaly made subtrae whic an becatlyzed byfirely uciferase (nzymatic reaction shown below). D-Lucifern is

lyophilzed inthe form ofa monpotasium salt nd has ben purifed byHPLC toremove dhydrolucifern ad L-ucifern, both ofwhic

are competive inhbitors ofirefly uciferase. Itis mportan tonte, howevr, tha D-Lucifern can form dehydrolucifern ithe presnce of

ultraviolet ight and/or moisture. For this reason, prio treconstiuon, store in the dark a t-20°C.

原厂资料：

D-Luciferin, also known as beetle luciferin or (D-(-)-2-(6'-hydroxy-2'-benzothiazolyl)-thiazoline-4-carboxylic acid), has a formula weight of 318.41 and is a synthetically made substrate which can be catalyzed by firefly luciferase (enzymatic reaction shown below). D-Luciferin is lyophilized in the form of a monopotassium salt and has been purified by HPLC to remove dehydroluciferin and L-Luciferin, both of which are competitive inhibitors of firefly luciferase. It is important to note, however, that D-Luciferin can form dehydroluciferin in the presence of ultraviolet light and/or moisture. For this reason, prior to reconstitution, store in the dark at -20°C.

注意事项：

Store lyophilized D-Luciferin at -20 °C in the dark. Reconstitute lyophilized D-Luciferin with deionized water and bring the solution to a pH of 6.0 - 6.3 with HCl/NaOH. At a pH greater than 6.3, D-Luciferin may undergo a slow racemization from the D- to the L-isomer. After reconstitution, store at 4 °C and protected from light for up to 2 weeks or alternatively, store at -20 °C for up to 1 year [aliquoted and protected from light].
