Description
Firefly luciferase is a protein with a molecular weight of approximately 61 kDa. In the presence of ATP, magnesium ions, and oxygen, it can catalyze the oxidation of luciferin to oxyluciferin, during which a bioluminescence with a wavelength of around 560 nm is emitted.
Detection principle as shown in the figure:

YEASEN Biotech's Bright-One Step Luciferase Assay Kit features easy operation, high sensitivity, and strong signal intensity. It is suitable for experiments that require high sensitivity. There is no need to wash or collect cells before the experiment, and it can be used directly. The lysis and detection of cells are completed in one step, eliminating the need to mix reagents, saving experimental time.
Features
Long signal half-life: The signal half-life is 30 min, meeting the needs of high-throughput experiments.
Strong fluorescence signal: The signal value can reach 8 orders of magnitude, with a large detection window.
Convenient operation: One-step procedure, avoiding complicated experimental processes.
Applications
Signaling Pathway Research
Candidate Drug Screening
T Cell Killing Assay

This kit is compatible with the vast majority of mammalian cell lines and primary cells, including HEK293, HeLa, Jurkat, CHO, and NIH/3T3. The included cell lysis buffer achieves complete lysis of both adherent and suspension cultures. Yeast or bacterial cells are not recommended without protocol adaptation.
A luminometer or microplate reader with a luminescence detection mode is required. Standard fluorescence readers with excitation sources are not suitable. Compatible instruments include the Promega GloMax, BioTek Synergy, PerkinElmer EnVision, or equivalent luminometers. Ensure any injection system is primed before measurement to minimize signal delay.
Luciferase substrates are light-sensitive and mildly temperature-sensitive. Handle under subdued lighting. After preparing working dilutions, use within the timeframe specified in the datasheet (typically 30–60 minutes). Store concentrated substrate stocks at –20°C in amber or foil-wrapped tubes. Do not subject substrates to repeated freeze-thaw cycles.
The linear detection range exceeds 8 orders of magnitude of enzyme concentration, making this kit suitable for detecting both weak promoter activity and highly expressed reporter constructs without signal saturation. This wide dynamic range is particularly valuable for dose-response and titration experiments.
No. This kit is formulated for in vitro cell-based reporter gene assays using cell lysates. For in vivo bioluminescence imaging, use a D-luciferin or coelenterazine formulation validated for in vivo administration. This product is for Research Use Only (RUO) and is not intended for clinical, diagnostic, or in vivo imaging applications.
Yeasen Biotechnology offers flexible customization options for many of its assay kits and detection reagents, including custom lot sizes, bulk ordering, and application-specific formulation adjustments. Volume pricing, custom packaging, and kit bundling may be available depending on the product and intended workflow. A Certificate of Analysis (CoA) and lot-specific QC data are provided with every order. For inquiries regarding large-volume orders, custom configurations, or integration into automated workflows, please contact the BioHippo team for a tailored quotation.
