MicroRNAs Can Convert Normal Cells Into Cancer Promoters

Unraveling the mechanism that ovarian cancer cells use to change normal cells around them into cells that promote tumor growth has identified several new targets for treatment of this deadly disease.

DOWNSTREAM PROCESSING WHITE PAPERS & CASE STUDIES

  • Chromatography Column Protection With 3M Purification LifeASSURE™ PLA Series Membrane Filters Protective, or guard, filters are often used in chromatography column purification steps to protect the column media from contaminants in the various fluids that come in contact with the column.
  • Efficiency Test Of ReadyToProcess™ Columns

    ReadyToProcess™ columns are prepacked, prequalified, and presanitized process chromatography columns suited for purification of biopharmaceuticals (e.g., proteins, vaccines, plasmids, and viruses) for clinical phase I and II studies. ReadyToProcess columns are available with several media at different volumes (1, 2.5, 10, and 20 L).

  • Optimized Purity And Recovery Of A Monoclonal Antibody Using Mixed-Mode Chromatography Media

    Monoclonal antibodies (mAbs) remain a predominant class of therapeutic protein products on the market because of their wide range of applications in disease treatment and diagnosis. Over the years, upstream technology advancements have helped improve the titer of target antibodies, from merely 1 g/L two decades ago to 10–13 g/L in fed-batch processes and up to 25 g/L in perfusion cultures today (Gronemeyer et al. 2014).

  • 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

  • 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.

  • Determination Of kLa Values Of Single-Use Bioreactors

    Because single use bioreactors offered by  manufacturers vary in parameters critical for oxygen transfer, they are often not comparable to each other and to conventional glass and stainless steel vessels.
