Background:

D-luciferin is a cell-permeable chemiluminescent luciferase substrate with a Km of approximately 2 μM. D-luciferin could emit lights upon oxidative decarboxylation in the presence of ATP. D-luciferin provides a bioluminescent signal for in vivo and in vitro detection of cellular ATP levels. D-Luciferin chould be used to assay the expression of the luciferase gene linked to a promoter of interest. Alternatively, D-luciferin and luciferase can be used to assess ATP availability in cellular or biochemical assays. D-luciferin could be administrated intravenously or intraperitonealy. In vivo and in vitro bioluminescence imaging (BLI) is a promising technique for non-invasive tumour imaging. The repeat ability coefficients of intravenously and intraperitonealy was 80.2% and 95.0%, respectively. PEmax of IP was 5.6 times higher for IV. When compared with IP, IV administration showed better repeatability and better sensitivity. It would be more beneficial to evaluate the accurate tumor burden of the small tumors rather than the larger tumors [1].
