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

  • 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.
  • 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. 

  • 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.

  • Biomanufacturing Complexity

    This white paper addresses one of the most serious challenges facing biomanufacturing professionals today - how to understand and then deal with the extreme complexity associated with biotechnology manufacturing.

  • 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. 

  • Biological Contamination Events In Isolators: What Lessons Can Be Learned?

    Microbiological deviation and biological contamination events have been observed in pharmaceutical isolators including those used in production, sterility test and pharmacy aseptic services. By James Drinkwater, Bioquell UK Process & Compliance Director

With the Eppendorf BioSpectrometer basic, measurements can be executed in the UV and Vis range from 200 nm to 830 nm. The freely selectable wavelengths offer you maximum flexibility during these procedures.

The Aquasyn tank bottom valve is a reliable solution for your tank outlet needs, with its conical profile allows for complete drainability and the prevention of deadlegs or entrapment areas.

Sartopore 2 XLM filter cartridges are especially designed for validated sterilizing grade filtration and reliable Mycoplasma removal of cell culutre media.

Antibody against Macrophage/Macroglia-specific Protein, Iba1.

CHT is a leading purification medium of biomolecules in today’s demanding downstream process industry. Its mixed-mode support offers unique selectivities and often separates biomolecules that appear homogeneous with other chromatographic methods. The diverse binding capabilities of CHT for host cell proteins, leached protein A, antibody dimers and aggregates, nucleic acids, and viruses allow its use at any stage from initial capture to final polishing.

Agilent’s Gene Expression Wash Buffers are optimized and validated for consistently reliable, high volume, post-hybridization processing.

Natrix HD Membranes offer a breakthrough in membrane architecture that will forever change downstream purification. Available in two chemistries: Q (strong anion exchange) and Sb (strong cation exchange and hydrophobic group).
