  • Detection of NADH and NADPH with the Omega's High Speed, Full UV/Vis Absorbance Spectrometer

    Nicotinamide Adenine Dinucleotide (NAD+), reduced nicotinamide adenine dinucleotide (NADH), nicotinamide adenine dinucleotide phosphate (NADP+) and reduced nicotinamide adenine dinucleotide phosphate (NADPH) have been known to play vital roles in energy metabolism, antioxidation, and reductive biosynthesis. In recent years, these co-factors have been shown to be involved in other physiological functions as well, including aging, oxidative stress, intracellular calcium homeostasis, ROS production, cell death and gene expression. more

  • 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(). more

  • 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. more
