Combo Of Avastin, Second Drug Shows Promise Fighting Brain Cancer, Mayo Clinic Finds

The drug bevacizumab, also known by the trade name Avastin, shrinks tumors briefly in patients with an aggressive brain cancer known as glioblastoma multiforme, but then they often grow again and spread throughout the brain for reasons no one previously has understood.

  • Laser Spotlight Reveals Machine 'Climbing' DNA

    The experiments, reported in this week's Science, use laser light to generate very bright patches close to single cells. When coupled with fluorescent tags this 'spotlight' makes it possible to image the inner workings of cells fast enough to see how the molecular machines inside change size, shape, and composition in the presence of DNA.

  • Researchers 'Watch' Antibiotics Attack Tuberculosis Bacteria Inside Cells

    Weill Cornell Medical College researchers report that mass spectrometry, a tool currently used to detect and measure proteins and lipids, can also now allow biologists to "see" for the first time exactly how drugs work inside living cells to kill infectious microbes.

  • Researchers 'Switch Off' Neurodegeneration In Mice

    Researchers at the Medical Research Council (MRC) Toxicology Unit at the University of Leicester have identified a major pathway leading to brain cell death in mice with neurodegenerative disease. The team was able to block the pathway, preventing brain cell death and increasing survival in the mice.

  • Accelerating Biopharmaceutical Development From DNA To Drug

    In the last decade, single-use solutions for virtually every bioprocess unit have been developed, and considerable investments have been made by the industry into areas that underpin this technology.

  • Managing Cell-Based Potency Assays: From Development To Lifecycle Maintenance

    Characterization of a biological product — which includes the determination of physicochemical properties, biological activity, immunochemical properties, purity and impurities — is necessary to establish the safety and efficacy profile of a given product (ICH Q6B).  By Dr. Weihong Wang, manager, Molecular and Cell Biology, Eurofins Lancaster Laboratories

  • Avoiding Drug Shortages With Microbial Detection

    Over the past year, critical drug shortages used to treat a host of life-threatening illnesses have been making headlines. Microbial contamination has been cited as a major contributor to the shortage, yet the prevailing practices to ensure the safety of drugs have been slow to change. In most cases, quality assurance practices safeguarding the drug making environment continue to rely on periodic air and a culturing method from a prior century. By Aric Meares, President and CEO, BioVigilant

  • Met One Sensors Resistant To Vaporous Hydrogen Peroxide (VHP) Pharmaceutical manufacturers often require an aseptic production environment to minimize the presence of microbes and their potential contamination of the manufactured product.
  • White Paper: Comparability Of The Cell-Freeze® (Charter Medical) Freezing Bag To The Cryocyte™ (Baxter) Bag For Cryogenic Storage Of Human Hematopoietic Progenitor Cells Successful cryopreservation of hematopoietic progenitor cells (HPC) is dependent upon a number of factors, including the biopreservation media, freezing rates, and storage using sterile, cryogenically durable storage bags. The Cell-Freeze® cryogenic storage containers are 510(k) cleared for storage, preservation and transfer of hematopoietic progenitor stem cells (HPC’s). By Charter Medical, Ltd.
  • Materials Of Construction For Biopharmaceutical Water Systems

    Stainless steels are uniquely qualified for bioprocessing applications not only because of their long service life, availability, and fabricability, but also because they are non-corroding, non-contaminant, can be polished to very smooth finishes, are strong and rigid, can withstand heat and chemical sterilization treatments, and are easily welded. By Michelle M. Gonzalez

The ATF™ System was originally designed for perfusion processes in mammalian cell culture, using hollow fiber filters to achieve an efficient cell separation with low shear and allowing robust large scale manufacturing.

Sartopure PP2 Cartridges were optimized for the wide range of prefiltration.

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.

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.

Polyethylene (PE) and PTFE hydrophobic membranes for economical air / gas and vent filtration. Virus, bacteria and spore retentive. PE is gamma stable and will substitute PVDF. Retention ratings from 0.01um in gas applications or 0.1um in liquid applications, to 10um.

PES, Nylon or Cellulose Acetate hydrophilic membranes provide performance improvements over other membrane types like PVDF. Microbially retentive micron ratings from 0.04um, 0.1um and 0.2um to prefilter ratings 0.45um, 0.65um and up to 1.2um.

ZenPure designs, mold-manufactures and injects its own filter components. Engineering, product development and filter production under ISO standards facilitate full quality audit and traceability to meet the highest industry standards. Validation support documentation is available for appropriate products.

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.

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.
