Enzyme Kinetic Measurements for a Combinatorial Library of Inhibitors of Pseudomonas Elastase
Pseudomonas elastase (LasB) is a key drug target in various chronic and intractable infections. A library of 160 potential, in-house synthesised, elastase inhibitors were screened using a fluorescence assay with the internally quenched substrate Abz-Ala-Gly-Leu-Ala-Nba. Enzymatic kinetic measurements were done on a FLUOstar OPTIMA and Km and Vmax values were calculated for each inhibitor using the MARS Data Analysis software...

ORAC Assay Performed on the POLARstar Omega and PHERAstar FS microplate reader
In all oxygen consuming cells, metabolism and oxidative stress generate several intermediates and byproducts that are collectively known as reactive oxygen species (ROS). ROS are necessary intermediates in the human body, but they are also involved in the aging process and in the development of many degenerative diseases, including cancer, heart disease, Alzheimer's and Parkinson's. Herein we describe the determination of the antioxidant capacity of different fruit juices using the ORAC assay; a standardized method that uses Trolox®, a water-soluble analogue of vitamin E, as a standard substance...

Analysis of Prostate Tumour Cell Invasion Using BD FluoroBlokTMand FLUOstar OPTIMA
Real-time analysis of tumour cell invasion with a FLUOstar OPTIMA enclosed in an AtmosBag
The FLUOstar OPTIMA is used for reading the BD Biosciences FluoroBlok(TM) tumour cell invasion system. In this application note we show that the results are comparable to the traditional invasion assays. The introduced method is fast, saving time and labour. The FLUOstar OPTIMA is able to take multiple readings over time at a user defined temperature...

Homogeneous IgG AlphaLISA® assay performed on BMG LABTECH's PHERAstar Plus
Z' value of 0.92 indicates a highly robust assay combined with high quality instrumentation
Immunoglobulins or antibodies are proteins that are involved in the immune response. That makes them interesting drug targets. This application note shows the detection of the immunoglobulin IgG using an AlphaLISA® assay performed on BMG LABTECH's PHERAstar Plus. The AlphaLISA® technology utilizes oxygen to start a cascade of chemical reactions resulting in a luminescence signal at 615 nm. Sensitivity and Z´values obtained in different plate formats are presented....

Predictor(TM) hERG Fluorescence Polarization Assay Kit performed on the PHERAstar/PHERAstar Plus
The potential for cardiotoxic side-effects continues to challenge the development of small molecule based therapies. These intolerable side-effects are often precipitated by drug-induced long QT syndrome (LQT), which is often linked to blocking the human ether-a-go-go related gene (hERG) potassium channel. Although patch-clamp electrophysiology remains the gold standard for determining the interaction of compounds with the function of the hERG channel, radioligand displacement assays have proven to be a cost-effective initial alternative assay for hERG channel liability at early stages of compound development....
