The Real Threat To Biopharma Supply Chains: Bioprocessing MaterialsThe COVID-19 induced risk to biopharma is not a shortage of pharmaceutical ingredients. It’s the constricting supply of consumable materials and equipment necessary to produce therapies from them. Mike Piccarreta, Partner at Kearney, offers an outlook and practical advice on supply stabilization in this BioProcess Online exclusive.

New Nanoparticles Shrink Tumors In Mice
MIT researchers have developed RNA-delivering nanoparticles that allow for rapid screening of new drug targets in mice. In their first mouse study, done with researchers at Dana-Farber Cancer Institute and the Broad Institute, they showed that nanoparticles that target a protein known as ID4 can shrink ovarian tumors.

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.

Improving DNA Removal from Bioprocess Purification Processes
Many new biological drug products produced using recombinant DNA technology, such as monoclonal antibodies, are produced in cell culture. Because therapeutic proteins such as monoclonal antibodies are produced in cell culture, impurities can result from the host cells, or cell substrates. By 3M Purification Inc.

DOWNSTREAM PROCESSING PRODUCTS
Resin are designed specifically for intermediate purification steps that remove host-cell contaminants from partially purified targets using strong or weak hydrophobic interactions. Methacrylate-based beads for protein and nucleic acid purification using hydrophobic interactions are available for purifying compounds that have weak or strong hydrophobic regions.
Magnosphere™ is a superparamagnetic particle for in vitro diagnostics and bio research applications.
Macro-Prep hydrophobic interaction chromatography (HIC) media are methacrylate-based, 50 µm beads used for protein, polypeptide, enzyme, and nucleic acid purification.
