EasyLife™ L—An Exceptionally Fast, Sensitive and Accurate Luminescence Spectrometer for LRET Assays and General Luminescence
The EasyLife™ L is a unique, affordable solution machine. Using our proprietary single shot detection technique, the EasyLife™ L obtains the maximum information about any molecular system, something you simply cannot get with conventional fluorescence techniques. |

Due to its unique ‘single-shot’ detection technique, the EasyLife™ L is lightening fast. It can measure up to 500 complete decays in a second. The decays are instantly analyzed in real time enabling the user to follow reaction kinetics by plotting the lanthanide lifetime rather than the intensity as a function of time. This is the basis for a new, unique feature that only EasyLife™ L can offer: the Timebased Lifetime Scan. This makes the experiment immune to artifacts that usually affect intensity, such as light scattering, concentration fluctuations, precipitation etc. The lifetime-based technique is ideal for sensing applications, where binding of a substrate changes the lanthanide lifetime.
- LRET based kinase activity assays
- Conformational changes in ligand-binding glutamate receptor
- Sigma factor binding to RNA polymerase
- K+ channel voltage sensor movement in cell membranes
- Detection of salicylic acid in blood by sensitized Tb luminescence
- Assays for determining antibiotics (norfloxacin, garenoxacin, grepafloxacin) in urine and serum
- DNA-lanthanide assays for multi-drug resistance of TB strains

The binding kinetics of Tb3+ to DNA can be followed free of intensity artifacts by using the unique Timebased Lifetime Scan. Here the EasyLife™ L performs continuous rapid measurements of the average terbium lifetime in real time. |
DNA-lanthanide assays are used in a number of diagnostic tests, for example DNA-Tb3+ in testing for antibiotic resistance of tuberculosis strains. Terbium luminescence is enhanced upon binding to DNA, which results in 3 fold increase of Tb3+ lifetime. |
