UA-Glo® Bio-luc Luciferase Assay System

The UA-Glo® Bio-luc Fluorescent Lactate Dehydrogenase Assay Kit can be used for quantitative detection of the expression level of reporter gene luciferase in cells. The kit is a homogeneous reagent and only requires one sample addition for testing, reducing the experimental errors that may be caused by multiple sample additions. This reagent has the characteristics of high signal-to-noise ratio, good repeatability, and good stability. Its stable luminescent signal makes this product particularly suitable for high-throughput screening experiments of compounds. The chemical stability of the UA-Glo® Bio-luc Fluorescent Lactate Dehydrogenase Assay Kit is better. The detection signal intensity of the assay reagent can be reduced by less than 15% when stored at 4°C for 5 days, making it convenient for customers who need to repeatedly use the kit within a short period of time.

UA-Glo® Bio-luc Luciferase Assay Kit** detects the activity of the firefly luciferase reporter gene in cells through a luciferase reaction. The luciferase reaction is highly sensitive, and parameters such as pH, temperature, and experimental system settings have a significant impact on the reaction. Under most experimental conditions, direct comparison of absolute detection values between samples is not recommended. It is advised to set up the same reference control on each assay plate, and normalize the detection values of experimental samples against those of the reference control and vehicle control before data processing and comparison.

1) Seed the experimental cells expressing the firefly luciferase reporter gene at an appropriate density in a white, transparent-bottom 96-well or 384-well cell culture plate according to experimental requirements.  
2) After treating the cells as required by the experiment, proceed with the luciferase reporter gene assay.  
3) Take out the UA-Glo® Bio-luc Luciferase Assay reagent. After complete thawing, equilibrate to room temperature (22°C–25°C) and mix thoroughly by inverting. The luciferase reaction is sensitive to temperature changes. Both the assay reagent and the cell plate must be equilibrated to room temperature, and the temperature should be kept constant (±1°C) during the assay.  
4) Remove the experimental cell plate and equilibrate to room temperature.  
5) Add an equal volume of assay reagent to the culture medium in each well of the cell plate. For example, add 100 µL of assay reagent to wells of a 96-well plate containing 100 µL of cells, or 20 µL of assay reagent to wells of a 384-well plate containing 20 µL of cells.  
6) Shake the plate at medium speed for 1 minute, then incubate in the dark for 10 minutes to stabilize the luminescence signal.  
7) Measure the luminescence signal using a luminometer or a multimode plate reader. It is recommended to read the plate within 1 hour.

1) Different batches should not be mixed.
2) Without strict verification, it is not recommended to change the dosage of the test reagents.
3) For research purposes only.
