ry10_25 Whitehead Scientists Identify Major Flaw In Standard Approach To Global Gene Expression Analysis

Whitehead Institute researchers report that common assumptions employed in the generation and interpretation of data from global gene expression analyses can lead to seriously flawed conclusions about gene activity and cell behavior in a wide range of current biological research. By Nicole Giese Rura

  • 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.

  • Improving Aggregate Removal From mAb Feed Using Cation Exchange Chromatography

    Researchers in the field of chromatography have required ever more sophisticated and selective methods for removing aggregates from the monomer.

  • Optimized Purity And Recovery Of A Monoclonal Antibody Using Mixed-Mode Chromatography Media

    Monoclonal antibodies (mAbs) remain a predominant class of therapeutic protein products on the market because of their wide range of applications in disease treatment and diagnosis. Over the years, upstream technology advancements have helped improve the titer of target antibodies, from merely 1 g/L two decades ago to 10–13 g/L in fed-batch processes and up to 25 g/L in perfusion cultures today (Gronemeyer et al. 2014).

  • 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

  • Sani-Tech® Ultra White Paper

    For several years, pharmaceutical manufacturing professionals have increasingly stated concerns about material leachables and extractables and their impact on the products they produce. Fluid transfer systems that include flexible tubing have been at the forefront of this discussion. 

  • Microbial Fermentation In Single-Use Xcellerex™ XDR-50 MO Fermentor System

    This application note describes the performance of a single-use Xcellerex XDR-50 bioreactor system when used in cultivations of E. coli and of modified Pseudomonas fluorecsens (P. fluorescens) producing a monoclonal antibody (MAb). Both the achieved microbe densities and product yield were shown to be consistent with the performance of conventional stainless steel systems.
