Latest Application Notes

Measurement of the mitochondrial membrane potential is useful in a variety of research areas. Mitochondrial membrane potential is usually measured using non-invasive cationic dyes. These dyes are sequestered into the mitochondrial matrix in amounts directly proportional to the membrane potential. BMG LABTECH’s FLUOstar Omega was used in an hts assay measuring mitochondrial membrane potential in human cells. The results presented here were gained using primary human fibroblast cells from controls

Poly (ADP-ribose) polymerases (PARP) transfer ADP-ribose to itself and other nuclear proteins such as histones, therefore PARP play a crucial role in regulating DNA repair. A luminescent cellular PARP assay and a fluorescent cell viability assay were performed on BMG LABTECH’s FLUOstar Omega to evaluate PARP inhibitors. PARP inhibition has been demonstrated to potentiate the cytotoxicity of anti-cancer drugs and ionising radiation. The ability of the FLUOstar Omega to measure absorbance, lumines

Laser nephelometry has been shown to be a reliable technique for the measurement of drug solubility in 96-well plate format. In this note the use of BMG LABTECH´s NEPHELOstar to investigate the effects of complexation on the drug antimycotic activity is described. Laser nephelometry can distinguish between the concentration at which the drug just goes into or just comes out of solution. This is presented in phase solubility studies. Furthermore nephelometry was used to monitor fungal growth.

Transcreener™ ADP2 Assay kits are far-red competitive fluorescence polarization immunoassays based on the detection of ADP. Any enzymatic reaction that uses ATP in a range from 0.1-1000 µM can be monitored. With its dual emission detection and five photomultiplier tubes, BMG LABTECH´s PHERAstar Plus provides the speed and sensitivity needed to take full advantage of BellBrook Labs Transcreener™ technology. Furthermore, a specific optical module was developed, thereby making assay setup simple.

Reaction optimisation work using traditional techniques can be complex, time consuming and expensive, but is a vital part of the development of all chemical processes. One approach is the use of statistical experimental design (DoE). This application note gives some guidance on DoE and it’s use with the Africa system.
