D-Luciferin, Potassium Salt D -1g

D-Luciferin, Potassium Salt is a high-purity substrate commonly used in bioluminescent assays involving luciferase enzymes. This D-isomer is specifically recognized by firefly luciferase, producing a strong and measurable light signal in the presence of ATP and oxygen. It is ideal for in vitro and in vivo imaging, reporter gene assays, and cell-based luminescence detection.
