Closer Look At Cell Membrane Shows Cholesterol 'Keeping Order'

Cell membranes form the “skin” of most every cell in your body, but the ability to view them up close and in motion cannot be rendered by many experimental techniques. A team of scientists working at the National Institute of Standards and Technology (NIST) and University of California, Irvine, recently developed a way to magnify them dramatically.

  • Applications And Integration Of Hydrogen Peroxide Vapor For Biotech/Bioprocess

    The increase in size and scale of bio-processing is presenting a new challenge. Traditional methods of sterilisation, to maintain clean facilities, are becoming difficult to deploy in a controlled and regulatory compliant way. By Richard Lucas, Ph.D., Bioquell UK Ltd.

  • Automated Bioluminescent ADCC Reporter Bioassay Using Bioengineered Jurkat Cells

    Pharmaceutical companies are increasingly exploring new biologic and biosimilar products, and thus increasing monoclonal antibody (mAb) immunotherapeutic research. By Tracy Worzella, Promega Corporation and Brad Larson, Applications Department, BioTek Instruments, Inc.

  • Automation Of A Homogeneous Proximity Assay For Detection Of Residual Protein A In Biological Therapeutics

    Protein A is used in affinity chromatography for therapeutic antibody purification and has been shown to leach from columns during purification of antibodies resulting in contamination. Residual Protein A in therapeutic drugs could elicit mitogenic or immunological reactions in patients.

  • Turning Data Into Information

    As biopharmaceutical manufacturing has evolved from small-scale lab production in small flasks to massive commercial production in deep-tank bioreactors, an avalanche of production data has evolved to support it. From individual unit operation skids to distributed control systems and enterprise resource planning tools, biomanufacturing today is buried by the sheer quantity of data coming in from the manufacturing floor.

  • The Challenge of Measuring Total Organic Carbon In Modern Pharmaceutical Water Systems

    Total Organic Carbon (TOC) is one of the quality attributes defined in the European and USA pharmacopoeias for pharmaceutical waters. Modern water treatment systems can deliver such high purity water that TOC levels can be consistently close to zero and very difficult to measure with any accuracy. This paper discusses some of the challenges when using TOC analysers to demonstrate pharmacopoeial TOC level compliance for modern water systems in the light of the ICH Q2 document from the International Conference on Harmonisation.

  • Micro-Volume Determination Of Labeling Efficiency In A Standard Microplate Reader

    A variety of methods and reagents have been developed to efficiently label biomolecules. By Peter J. Brescia, Applications Scientist,  BioTek Instruments, Inc.

CHT is a leading purification medium of biomolecules in today’s demanding downstream process industry. Its mixed-mode support offers unique selectivities and often separates biomolecules that appear homogeneous with other chromatographic methods. The diverse binding capabilities of CHT for host cell proteins, leached protein A, antibody dimers and aggregates, nucleic acids, and viruses allow its use at any stage from initial capture to final polishing.

3M Purification Inc.’s LifeASSURE™ PDA series filter combines two asymmetric polyethersulfone (PES) membrane layers together with proprietary Advanced Pleat Technology (APT) design.

Baumann 85000 sanitary pinch valves are intended for use with up to 3/4 inch O.D. pharmaceutical grade tubing. They are designed to couple FIELDVUE™ digital valve controller intelligence with a linear actuator and tube shell.
