New Insights Into HIV Vaccine Protection Will Improve Drug Development

Four years ago, a potential HIV vaccine showed promise against the virus that causes AIDS, but it fell short of providing the broad protection necessary to stem the spread of disease.

  • 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. 

  • Mammalian Virus Purification Using Ceramic Hydroxyapatite

    Conventional techniques for mammalian virus purification produce variable quality, quantity, and significant loss of particle infectivity. We  propose the chromatographic separation of viral particles of diverse sizes and from different families such as dengue, influenza, mouse hepatitis, adenovirus, poliovirus using CHT Ceramic Hydroxyapatite resin.

  • Automating Protein Purification Processes Achieves Reliable Results And Reproducibility

    ÄKTA start is an easy-to-use, reliable protein purification system. In this application note it is described how Erica, a post-doctoral researcher, used ÄKTA start to purify GST-tagged protein using a predefined method template, a GSTrap FF column, and a Frac30 fraction collector. 

  • 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).

  • 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.

  • Rapid Chemically-Defined Feed Media Development to Improve Simulated Cell Culture Processes

    Implementing an optimized feed medium may be the most effective alternative for modifications to the growth medium in an existing process.
