DOWNSTREAM PROCESSING FEATURED ARTICLES

A Welcome Predictability

Synthetic biology is the latest and most advanced phase of genetic engineering, holding great promise for helping to solve some of the world's most intractable problems, including the sustainable production of energy fuels and critical medical drugs, and the safe removal of toxic and radioactive waste from the environment.

DOWNSTREAM PROCESSING WHITE PAPERS & CASE STUDIES

  • 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.

  • Efficiency Test Of ReadyToProcess™ Columns

    ReadyToProcess™ columns are prepacked, prequalified, and presanitized process chromatography columns suited for purification of biopharmaceuticals (e.g., proteins, vaccines, plasmids, and viruses) for clinical phase I and II studies. ReadyToProcess columns are available with several media at different volumes (1, 2.5, 10, and 20 L).

  • Automating Protein Purification Processes Achieves Reliable Results And Reproducibility

    ÄKTA start is an easy-to-use, reliable protein purification system. In this application note it is described how Erica, a post-doctoral researcher, used ÄKTA start to purify GST-tagged protein using a predefined method template, a GSTrap FF column, and a Frac30 fraction collector. 

  • A Purification Strategy For Clinical-Grade Monoclonal Antibody

    mAbs are currently the most important class of therapeutic proteins. Advances in upstream process technologies have led to tremendous improvement of mAb titers in mammalian cell culture. 

  • USP <787> Small Volume Testing With Liquid Particle Counters

    By their very nature, biological therapeutics are not only expensive to manufacture but are often produced in small volumes.

DOWNSTREAM PROCESSING PRODUCTS

Bio-Beads SM-2 nonpolar polystyrene adsorbents are analytical grade, neutral macroporous polymeric beads for use in hydrophobic interaction chromatography.

DNA methylation events are heritable modifications that regulate gene expression without altering the DNA sequence itself. They serve as regulatory mechanisms for a wide range of biological processes and genetic diseases, and irregular methylation patterns have been associated with certain cancers.
Proyield Soy SE50MAF-UF is a protein hydrolysate derived from soy protein by enzymatic hydrolysis. The enzymes used for digestion are from non-animal sources. Proyield Soy SE50MAF-UF has been ultrafiltered to reduce endotoxin.

PRP-X300 is a polymeric column packing for the separation of alcohols and organic acids.

The Avanti J-30I High-Performance Centrifuge System gives you the fastest separations possible - in the shortest amount of time. Swinging-bucket and fixed-angle rotors provide maximum separation forces in excess of 100,000 x g at speeds up to 30,000 rpm.
The Pyros Kinetix® Flex is an optical tube reader that runs both chromogenic and turbidimetric assays in compliance with the USP, EP, and JP bacterial endotoxin test chapters.

PureFlo hydrophobic polyethylene (PE) membrane filters, gamma compatible and ideal alternative to PVDF. Mold injected capsules with multiple inlet / outlet options including sanitary ‘T’ clamps, hose barbs, quick sanitary connectors, elbows and threads. Almost any combination of connecting inlet or outlet is possible with over 30 options. High gas flow at low differential pressure due to encapsulation geometries and polyethylene (PE) membrane. Full validation supporting documents are available. Ideal for tube sets and hook up to bioreactors, fermenters, biocontainer, biobags, wave bags or single use fermenters.

ZenPure’s in-company mold design and injection capabilities, filter production and quality assurance facilitate manufacturing audit and product traceability that meet the highest industry standards.

The Allegra X-30 Series Benchtop Centrifuges were designed with your needs in mind providing you with excellent performance and easy operation in a compact design that saves you valuable time and laboratory space.

DOWNSTREAM PROCESSING MULTIMEDIA

Bioprocess With The Bozenhardts is back, with a fresh episode packed with advice from Herman and Erich on the selection of filling systems for biopharmas. Listen in as the Bozenhardts give us an update on the process, logistics, and administration trends that are informing filling system decisions today, and offer direction on making choices that will prepare you for the fast-advancing therapies of tomorrow.

Beckman Coulter's Randall Lockner, marketing manager for centrifugation, explains the highlights of the floor model ultracentrifuge, the Optima X Series.

Bio-Rad now offers two very high capacity ion exchangers: Nuvia S, which can be used for capture and/or intermediate polishing; and Nuvia Q, which can be used for intermediate and/or final polishing.
