3、催化物发光昆产典型的黄绿光。体外研究 D-luciferin is the natural substrate of the enzyme luciferase (Luc), that catalyzes the production of the typicalyellowgreen light of fireflies.The present review covers the synthesis of D-luciferin and derivatives oranalogues that are substrates or inhibitors of the luciferase fr

4、om the American firefly Photinus pyralis, theenzyme more frequently used in techniques of in vitro and optical imaging 1.1/2 Master of Small Molecules 您边的抑制剂师www.MedChemE体内研究 Bioluminescence imaging (BLI) using the firefly luciferase (Fluc) as a reporter gene and D-luciferin as asubstrate is current

5、ly the most widely employed technique. The total signal intensity is plotted against thetime after D-luciferin injection to generate a time-intensity curve. In addition to the peak signal, the signals atfixed time points (5, 10, 15, and 20min) after D-luciferin injection are determined as alternativ

6、es to the peaksignal. The signal in a given time-intensity curve is normalized for the peak signal in the curve to representthe pattern of temporal changes after D-luciferin injection 2.PROTOCOLAnimal Mice 2Administration 2 In vivo BLI is performed using a cooled charge-coupled device camera system

Mice are injected with 75mg/kg D-luciferin in 100L of phosphate-buffered saline subcutaneously near the scapula and were placedin the light-tight chamber of the imaging system under isofl

8、urane anesthesia. Beginning 5min after injection,dorsal luminescent images with an exposure time of 1s are acquired sequentially at a rate of one image permin until 20min after D-luciferin injection. Data acquisition is continued until 40min postinjection on days 3 or5 and until 25min on day 7, beca
