D-Luciferin potassium is the potassium salt of D-luciferin, the natural substrate for firefly luciferase. In the presence of luciferase and ATP it produces a yellow-green bioluminescent signal (peak ~560 nm) used for luciferase assays and bioluminescence imaging. Supplied as a 10 mM ready-to-use solution (1 mL), it provides high purity and convenient handling for assay workflows.

• High purity: 99.97% by supplier analysis.
• Ready-to-use 10 mM stock for rapid assay setup.
• Generates strong bioluminescent signal with peak emission near 560 nm.
• Soluble in water (≈54.6 mM) with warming and sonication as needed.
• Suitable for luciferase reporter assays and bioluminescence imaging applications.
• Storage: sealed, protected from moisture and light; in solution store at -80°C for long-term stability.
