Redefining Sensitivity Standards: The UA-Luc 4 Luciferase Assay Kit, Born for Ultimate Discovery.

In cutting-edge life science research, the luciferase reporter gene system has consistently served as a "guiding light," illuminating the inner workings of cells. It is widely applied in core areas such as signaling pathway analysis, transcriptional regulation studies, receptor function exploration, and high-throughput drug screening. Its principle lies in the fact that the expression level of intracellular luciferase can be precisely quantified by measuring the intensity of cold light produced through substrate catalysis, thereby directly reflecting the activity level of the target gene.

However, traditional luciferase assays often face challenges like insufficient sensitivity, cumbersome procedures, or the need for cell destruction. The introduction of the UA-Luc 4 Luci/Gaussia Luciferase Assay Kit now completely overcomes these limitations, providing researchers with an unprecedented, ultra-sensitive, and non-destructive detection solution.

Why Choose UA-Luc 4? Revolutionary Performance Enhancements

The UA-Luc 4 is a homogeneous, ready-to-use kit specifically designed for detecting secreted Gaussia Luciferase (GLuc). It is more than just a tool; it is your strategic partner in accelerating scientific discovery.

Core Advantages & Highlights:

• Ultra-High Sensitivity by an Order of Magnitude:
  Compared to similar mainstream international brand products, UA-Luc 4 achieves a leap in detection sensitivity by an order of magnitude. This enables the precise capture of extremely weak signals undetectable by traditional methods, revealing deeper biological phenomena. It is particularly suitable for low-expression cell models and the precise screening of high-potency inhibitory compounds.
  

• Simplified "Add-Mix-Detect" Workflow:
  As a homogeneous, ready-to-use reagent, UA-Luc 4 requires no complex preliminary preparation. The entire detection process is streamlined into a single step: simply mix the cell culture supernatant with the detection reagent and proceed directly to reading. This significantly saves time, reduces operational errors, and easily enables high-throughput screening.
  
  

• Perfect for Non-Destructive Analysis:
  Leveraging the secretory nature of Gaussia luciferase, you only need to collect a small amount of culture supernatant to complete the assay, entirely without cell lysis. The cells remain viable after detection and can be used for subsequent experiments such as cell viability assays, apoptosis analysis, or other biological tests, maximizing data dimensions and sample value.
  
  

• Excellent Signal-to-Noise Ratio and Stability:
  The optimized reagent formulation ensures very low background and stable signal output, delivering higher reliability and reproducibility for your research data.

UA-Luc 4 Lucia/Gaussia Luminescence Detection Kit Product Data

Signal Stability Test: THP1-Dual cells (5x10⁴/ml) were seeded in a 12-well plate and stimulated with 2'3'-cGAMP (final concentration 3 µg/ml) for 24 hours. The supernatant was collected for enzyme activity analysis. The assay was performed according to the kit instructions: 50 µl detection reagent + 20 µl supernatant, mixed, and luminescence was measured at different time points.

Detection Sensitivity and Window Comparison: THP1-Dual cells (5x10⁴/ml) were seeded in a 12-well plate and stimulated with 2'3'-cGAMP (final concentration 3 µg/ml) for 24 hours. The supernatant was collected for enzyme activity analysis. The assay was performed according to the kit instructions: 50 µl detection reagent + 20 µl supernatant, mixed, and luminescence was measured. The readings in the table represent the average of two duplicate wells. The results show that UA-Luc 4 Lucia/Gaussia is significantly superior to the international brand product at high, medium, and low enzyme concentrations, with detection sensitivity approximately one order of magnitude higher.
