NIH Scientists Shed Light On Mystery Surrounding Hepatitis B Virus

Scientists from the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), part of the National Institutes of Health, and the University of Oxford, U.K., have shed light on a long-standing enigma about the structure of a protein related to the Hepatitis B virus.

DOWNSTREAM PROCESSING WHITE PAPERS & CASE STUDIES

  • White Paper: Economic Analysis Of Single-Use Tangential Flow Filtration For Biopharmaceutical Applications Prior to creating an accurate economic model for TFF, a thorough understanding of the process where the TFF is used is needed. A process model is a valuable tool when properly executed and it must accurately include all critical aspects of the purification process. By Michael LaBreck, Mark Perreault, Novasep
  • Proven Long Life Lasers™ In Optical Particle Counters Optical particle counters (OPC) utilize light illumination and extinction to determine the presence, size, number and/or concentration of particles. Particles are typically suspended in a fluid or air, which flow through the volume that is illuminated and viewed by the detection system.
  • Accelerating Biopharmaceutical Development From DNA To Drug

    In the last decade, single-use solutions for virtually every bioprocess unit have been developed, and considerable investments have been made by the industry into areas that underpin this technology.

  • Connection Technology Advances Closed System Processing

    The global demand for new biologics and vaccines, combined with the growing emergence of biosimiliars, is challenging drugmakers to re-evaluate their processes and seek ways to make them more flexible, reliable, and cost-effective. By John Boehm, Colder Products Company

  • Mammalian Virus Purification Using Ceramic Hydroxyapatite

    Conventional techniques for mammalian virus purification produce variable quality, quantity, and significant loss of particle infectivity. We  propose the chromatographic separation of viral particles of diverse sizes and from different families such as dengue, influenza, mouse hepatitis, adenovirus, poliovirus using CHT Ceramic Hydroxyapatite resin.

  • 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.
