• ISO 9001 Accreditation Enhances Lab901’s Reputation for Quality

  Lab901 announced that it has been awarded ISO 9001:2008 accreditation for manufacturing quality covering its ScreenTape® System for automated gel electrophoresis. ISO 9001:2008 addresses quality management systems and looks at, among other things, what an organisation does to fulfil a customer’s qua more

• Genetic Fingerprint unmasks Microbial Vandals

  For the first time DNA analysis can identify paper-degrading microorganisms. This is made possible by a molecular process developed for fungal infected documents at the University of Vienna with support from the Austrian Science Fund FWF. Fungal species can now be clearly identified by means of a DN more

• Dynal Biotech: Magnetic Bead Chromatography: No Columns Required

  Dynal Biotech, a subsidiary of Invitrogen Corporation announced the release of the first two products in its new proteomic preparation range - weak cation exchange (WCX) Dynabeads(r) and reversed phase chromatography (RPC) Dynabeads(r). These novel beads are an excellent alternative to chromatograph 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

• High Pure PCR Cleanup Micro Kit - Novel Flexibility for Nucleic Acid Purification
  

  Manual nucleic acid isolation with High Pure products is long approved by the scientific community. The product portfolio includes kits for isolation of genomic RNA and DNA, plasmid DNA as well as purification of reaction products. Key goal for all products is to offer optimal solutions suited for many different sample materials in order to reduce the number of different nucleic acid isolation kits necessary in modern molecular biology labs. more

• Real-Time PCR Quality Control for Gene Expression
  

  Quantitative real-time PCR (qPCR) has become the de facto standard for nucleic acid quantification. This achievement is due in large part to its sensitivity, specificity, accuracy, large dynamic range of linear quantification, and its speed. The qPCR technology has matured to a ready-to-use commonly available method in most molecular biology laboratories. Nevertheless, the reliability of the final quantification result depends heavily on all elements in the workflow, such as the quality of the input template (integrity and absence of inhibitors), the PCR assay (specificity, efficiency, limit of detection), and normalization strategy (validated reference genes). more
