In modern biomedical research, luciferase reporter gene assays have become indispensable tools for quantifying gene expression, signaling pathway activity, and drug target responses with exceptional sensitivity. By capturing the bioluminescent signal generated during the enzymatic oxidation of luciferase substrates—such as firefly luciferase—these assays enable real-time, noninvasive, and highly quantitative readouts of molecular events within living cells.
However, traditional luciferase assays often suffer from labor-intensive workflows, rapid signal decay, and batch-to-batch inconsistencies. Such limitations pose significant challenges for high-throughput drug discovery and regulatory-compliant biopharmaceutical development, where data accuracy, reproducibility, and operational simplicity are critical.
ICH-Guided Pre-Validation for Industrial-Grade Reliability
To meet the evolving demands of high-throughput and precision pharmacology, Yeasen Biotech has developed a new generation of Luciferase Reporter Gene Detection Reagents, rigorously prevalidated according to ICH Q2 guidelines.
This next-generation formulation empowers laboratories with pharmaceutical-grade reliability and simplified workflows.
Method validation highlights include:
- Linearity: Demonstrated excellent linear correlation (R² ≥ 0.99) across 1×10³–1×10⁵ cells, supporting a broad dynamic range.
- Specificity: Delivers highly selective signal capture with negligible background interference.
- Precision & Accuracy: Coefficient of variation (CV%) consistently below 10%, ensuring superior reproducibility.
- Repeatability: Stable and consistent results across multiple replicates and batches.

5-Minute One-Step Workflow for Instant Results
Traditional luciferase assays require multiple steps—cell lysis, centrifugation, buffer exchanges—that not only prolong the process but also increase the risk of manual errors and sample loss.
Yeasen’s one-component, one-step system revolutionizes this workflow:
- Lysis & Detection in One Step: Simply add the reagent directly to the cell suspension, pipette up and down five times, and incubate for five minutes to achieve complete cell lysis and signal generation.
- No Wash, No Buffer Change: Fully compatible with both adherent and suspension cells, eliminating the need for media removal or washing steps.
- Ready-to-Use Simplicity: With only one reagent required, the assay is immediately ready for detection—no mixing or additional reagents needed.
