High sensitive detection of follistatin by Imperacer®: an initial study on the way to analytical gene-doping tests
For the understanding of interactions in the muscle-growth directing myostatin-pathway and therefore also for the establishment of high sensitive detection strategies for gene-doping, detailed studies of protein concentration levels in biological matrices and appropriate highly sensitive analytic techniques for quantitative monitoring of these biomarkers are required. In this work, the development of a high sensitive assay for follistatin based on the Imperacer® technology is described. The quantification limit in human serum was found at 60 pg/ml in only 6 µl sample volume. With this initial assay we demonstrate the first application in a set of analytical tests for a high sensitive myostatin pathway related profiling....

Molecular Probes® NanoOrange® Assay Performed on BMG LABTECH FLUOstar OPTIMA Microplate Reader
The field of proteomics has expanded dramatically in recent years with research on a whole host of organisms. Techniques such as two dimensional difference gel electrophoresis (2D DIGE) require the accurate quantitation of protein, as up to three labelled samples can be loaded on a single gel for comparison. Assay methods for determining protein quantitation include absorbance at 280 nm(1), the Bradford assay(2), Lowry assay(3), BCA method(4) and more sensitive assays such as Fluoroprofile® (Sigma-Aldrich) and NanoOrange® (Molecular Probes®)5()....

Nature's Ingenuity Shows the Way
FusionOpticsTM - The New Dimension of Stereomicroscopy
Up to 80 percent of our experience of our visual environment takes place via our visual perception. Without spatial vision, we would hardly be able to stay oriented. In recent decades, the neurosciences have gained many insights into the complex processes by which our brain's visual cortex and cerebral cortex do the fascinating job of processing the signals originating from the eyes into an image. A study carried out jointly by Leica Microsystems and the Institute of Neuroinformatics at the University of Zurich and Swiss Federal Institute of Technology showed how flexible and powerfull our brain joins visual signals to create an optimal spatial image. The results provided the basis for an innovation in stereomicroscopy which, in terms of resolution and focus depth, has broken through limits that were previously impossible to overcome....

Bradford Assay Performed on BMG LABTECH“s FLUOstar Omega with new Evaluation Software
Determining the protein concentration of samples is a necessary and often used method in biochemistry. Different colorimetric protein assays have been developed. The most commonly used methods are the Bradford assay, the Lowry assay and the BCA assay. In this application note we demonstrate how to determine the protein concentration of samples by using the Bradford assay and the new FLUOstar Omega....

Sensible and self-monitoring
Online process for soft water control
For the generation of soft water are mostly used ion exchanging devices with generation of sodium chloride since the beginning of the Sixties. The generated soft water quality and soft water quantity are depending thereby on the static and dynamic characteristics of the softening plant in operation....
