Recursive Splicing Key In Large Gene Processing
Now, investigators at Carnegie Mellon University have discovered that a novel mechanism, called recursive splicing, removes long introns by steadily paring them down in a predictable fashion and joining the remaining exons

DOWNSTREAM PROCESSING WHITE PAPERS & CASE STUDIES

  • 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.

  • A Disposable Valve For Process Chromatography

    This case study discusses the need for a fully automated, disposable chromatography system which was PLC controlled and designed for use in a cGMP environment. The required applications for the chromatography system included contamination removal, and concentration and purification of biologically derived proteins used in the production of research and clinical materials. 

  • Guidelines For Proper Filtration And Delivery Of Samples To On-Line Process Analyzers

    Increasingly precise process control strategies, often linked to computer control, have accelerated the use of sophisticated on-line chemical composition analyzers in plant applications. Instruments such as gas and liquid chromatographs, ion chromatographs, laser optic instruments, atomic absorption instruments and specific ion analyzers, which were rarities in laboratories ten years ago, are now found routinely in plant settings. By Ken Perrotta, Division Engineering Manager

  • 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.

  • Top 10 Considerations When Selecting An Isolator Supplier

    While price is certainly an important reason for buying any piece of capital equipment, it is not always the top reason. There are important considerations to examine when selecting an isolator supplier.

  • White Paper: Capillary Electrophoresis — A Simple Technique

    In 1989, Beckman Instruments introduced the first fully automated capillary electrophoresis instrument (P/ACE™ 2000) to the scientific community. At that time, CE demonstrated exceptional resolving of selected compounds, but the new technology lacked a track record of applications. By Beckman Coulter, Inc.

The VHP® TS1000™ Tri-Scale Sensor boosts VHP® VICTORY™ Biodecontamination Cycle efficiency and effectiveness of room and facility biodecontamination ensuring that hydrogen peroxide vapor sterilant is adequately distributed. 

3M Purification's core filtration technologies address the most demanding applications in pharmaceutical processing for small molecule and active pharmaceutical ingredient (API) applications.

Proyield Cotton CNE50M-UF is a protein hydrolysate derived from cottonseed by enzymatic hydrolysis. The enzymes used for digestion are from non-animal sources. Proyield Cotton CNE50M-UF has been ultrafiltered to reduce endotoxin.
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.

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.

A wide selection of ion exchange resin is available in various particle sizes, ionic forms, and purity ranges to offer a variety of purification solutions for process applications. Nuvia ion exchange resins are a family of best-in-class ion exchangers built with exceptionally high capacities and excellent purification capabilities, providing process developers more flexibility and higher productivity. The Macro-Prep are rigid macroporous hydrophilic resin meet the demands of process-scale applications. Chemically and mechanically stable, the resin operate well at low and medium pressures.

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.

The Emphaze Hybrid Purifier is a new single-use clarifying device containing a multi-mechanism all synthetic Q-functional anion exchange media integrated with a fine particle, bioburden reduction membrane. The anion exchange media is comprised of a quaternary amine hydrogel supported by a fine fiber nonwoven scaffold. A combination of 3M technology platforms enables the hyperfunctionalization of a high purity polypropylene nonwoven with a covalently attached, thermally stable, water soluble polymer; the functional polymer accounts for roughly two-thirds of the mass of the anion exchange media. The bioburden reduction membrane is a highly asymmetric, high loading capacity polyamide membrane which has nine zones of decreasing pore size spanning a roughly 20X range and terminating with a 0.2 μm bioburden reduction rated pore size.
