• 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

• 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. more

• Enzymatic Protein Digest for Mass-spectrometric Analysis
  

  The main focus in proteomic studies is on the identification of proteins in given biological samples. Proteins isolated and separated from a given sample (e.g., whole cell lysates, blood or tissue, protein complexes) by immunoprecipitation or affinity chromatography or two-dimensional electrophoresis must be proteolytically cleaved in the course of sample preparation for identification and characterization. A reproducible cleavage pattern of digested proteins is a prerequisite for the unambiguous identification of these proteins by mass spectrometry (MS). more
