  • 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.

  • 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.

  • Removal Of Host Cell Proteins During Monoclonal Antibody Purification

    Protein A chromatography is a widely used and highly successful method of purifying recombinant monoclonal antibodies. However, since Protein A has high affinity for antibodies, harsh conditions such as low pH are often required to elute monoclonal antibodies from Protein A affinity columns. By 3M Purification Inc

  • Comparing The Automated Pipetting To Volumetric Glassware And Air Displacement Pipettes

    Analytical sample preparation is used in many industries such as forensics, environmental chemistry, mining, beer and wine fermentation and many others. Concentrated samples are diluted and analyzed via High Performance Liquid Chromatography, Gas Chromatography, Atomic Absorption, and/or Inductively Coupled Plasma Spectroscopy to name a few. Traditionally these samples are prepared using volumetric glassware, syringes and/or pipettes.

  • Gemin X Pharmaceuticals: Finding A Drug's Mechanism Of Action

    Gemin X, a pharmaceutical company focused on the discovery and development of advanced oncology
    therapeutics, approached Metabolon to run a metabolism profile for one of their compounds—GMX1777.

  • Effect Of Sterilization On Mechanical Properties Of Silicone Rubbers

    Silicone rubber is widely used in the pharmaceutical industry where sterilizability is an essential requirement for all fluid transfer equipment. Pharmaceutical products must be sterilized frequently and repeatedly by high level energy and/or chemical vapor in order to eliminate bacterial surface contamination.

In an effort to push science forward, WHEATON is manufacturing  a new line of membrane driven flasks for high density cell culture. The flasks are designed to enhance small scale bio-production for antibody and protein generation.

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.

A proven method for confirming protein purity and yield without the need for gel staining steps. Stain-free gels provide visual confirmation of protein purity and yield by gel electrophoresis in less than 30 minutes. Stain-free technology is perfect for drug discovery, drug development, and method development for preclinical research.

Macro-Prep hydrophobic interaction chromatography (HIC) media are methacrylate-based, 50 µm beads used for protein, polypeptide, enzyme, and nucleic acid purification.

Elevating your laboratory’s potential starts with the optimal tabletop ultracentrifuge. And the Optima MAX Series is the absolute top of the line. Reaching up to 150,000 rpm and over 1,000,000 x g, Optima MAX instruments set the standard in tabletop speed.

Recirculating hollow fiber systems have been used for a long time with mixed results. The recurring problem with these and all other cell retention systems is the difficulty in scaling up and staying sterile.
