  • Single-particle analysis and electron tomography

    Both single-particle analysis and electron tomography are special tools for the structural analysis of biological components by transmission electron microscopy. Single-particle analysis enables us to determine the structures of relatively large proteins and macromolecular complexes without crystallisation. Electron tomography is often used to visualise organelles and subcellular structures at ...

  • Correction of non-specific binding in RaPID assays

    Heterogeneous immunoassays are typically subject to a low level of direct binding of enzyme-antigen conjugate to the solid support surface. This binding results in a very small amount of positive bias. Users can correct for this bias by using the procedure presented below. Standard curves which serve to estimate pesticide (antigen) concentration in immunoassays are usually sigmodial. By using ...


  • Discrete or Continuous Flow Analysis – which is better?

    A wide variety of factors affect the choice of analytical instrument. These include target workload (samples/hour), variety of chemistries, methods required, bench space, staff availability etc. In the following article Lalicia Potter, Technical Sales & Support Director at SEAL Analytical, examines one of the common decisions facing laboratory managers. As the manufacturer of an ...

  • On-Line Nitrate/Nitrite Probes for BNR Process Control

    ABSTRACTReal time nitrogen monitoring plays an increasingly important role for the successful biological nutrient removal at wastewater treatment plants. Though traditionally dissolved oxygen has been the main process control parameter a greater understanding of the biological mechanisms and process conditions like nitrite/nitrate concentrations to achieve lower effluent values becomes necessary, ...
