  • An Automated Profiling Application For G9a Histone Methyltransferase And Bromodomain Proteins

    Due to several findings, G9a and BET bromodomain proteins have become the target for numberous drug discovery projects. In this study, we describe a novel, cell-based assay platform that uses the robust, yet simple Enzyme Fragment Complementation (EFC) Technology.

  • Compound Profiling And Toxicity

    Utilizing a systems approach to drug discovery has generated a multitude of high affinity compounds for various classes of molecular targets with different degrees of disease state validation.

  • 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

  • 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).

  • Important Parameters For Packing Nuvia HR-S Resin At Process Scale

    Process-scale production typically involves more than one column. The packing quality of each column affects the efficiency of the whole workflow and is an important validation criterion.

  • 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.

Proyield Soy SE70M-UF is protein hydrolysate derived from soy protein concentrate by enzymatic hydrolysis. The enzymes used for digestion are from non-animal sources. Proyield Soy SE70M-UF has been ultrafiltered to reduce endotoxin.

CHO Feed 3 is a chemically-defined protein-free feed medium of non-animal origin. Using Irvine Scientific’s Rational Culture Media Design™ approach, this formulation has been developed to achieve high growth kinetics and product yield in fed-batch processes.

High volume labs require simple, durable solutions to their centrifugation needs. Beckman Coulter’s Allegra® Series general purpose, benchtop centrifuges serve the needs of these labs by saving time, offering ease-of-use, and providing reliable design for endurance under the most exacting standards.

The Hamilton PRP™-C18 is a new HPLC column designed to provide high-efficiency, reversed-phase separations over an extended column life in nearly any mobile phase or pH.

Hydrophilic or hydrophobic membrane filter capsules and cartridges for sterilizing liquid or gas. More than 20 different inlet / outlet connections, with or without vents and drains. SIP / Autoclavable. Specify when gamma stability is required.

Polyethylene (PE) and PTFE hydrophobic membranes for economical air / gas and vent filtration. Virus, bacteria and spore retentive. PE is gamma stable and will substitute PVDF. Retention ratings from 0.01um in gas applications or 0.1um in liquid applications, to 10um.

PES, Nylon or Cellulose Acetate hydrophilic membranes provide performance improvements over other membrane types like PVDF. Microbially retentive micron ratings from 0.04um, 0.1um and 0.2um to prefilter ratings 0.45um, 0.65um and up to 1.2um.

ZenPure designs, mold-manufactures and injects its own filter components. Engineering, product development and filter production under ISO standards facilitate full quality audit and traceability to meet the highest industry standards. Validation support documentation is available for appropriate products.

Conductivity sensors measure the ability of a solution to conduct a current. The higher the concentration of ions in the solution, the higher the conductivity, which is measured in microSiemens (mS).
