Downstream Processing White Papers and Case Studies

41. Optimized Sterile Filtration of Pharmaceutical Solutions 11/12/2015

    The cost of filtration and separation stages within the production of pharmaceuticals has been increasing along with the increased complexity of final drug products.

42. USP <787> Small Volume Testing With Liquid Particle Counters

    By their very nature, biological therapeutics are not only expensive to manufacture but are often produced in small volumes.

43. Biomanufacturing Debottlenecking And Process Optimization 3/6/2012
    Optimizing biomanufacturing is particularly challenging because of variability and complexity associated with the sharing of finite and interdependent resources. By BIO-G
44. Fast Quantification Of Saliva Samples In Microplates 12/7/2012

    A successful evaluation study of saliva samples in microplates using Tecan’s Infinite F50 microplate reader in combination with Tecan’s Magellan™ data analysis software, using the Saliva Quantification Kit from Greiner Bio-One for the fast detection of saliva samples.

45. Avoiding Drug Shortages With Microbial Detection 3/6/2013

    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

46. CD69 Expression On Activated Lymphocytes Is Stable In Streck's Cyto-Chex® BCT 7/16/2012

    The purpose of this study was to determine if the activation marker, CD69, is preserved and stable in whole blood samples collected in Cyto-Chex® BCT. Previous studies have demonstrated CD marker stability of whole blood samples collected in Cyto-Chex BCT for up to 7 days when stored at room temperature (18-22°C).  By Jodi Alt, Ph.D

47. SciLog - Creating Advanced Biotech Equipment With Mettler Toledo 3/26/2012
    For nearly two decades, SciLog, Inc. has been dedicated to creating revolutionary single-use purification systems and disposable sensor technologies.
48. Automating Protein Purification Processes Achieves Reliable Results And Reproducibility 10/16/2013

    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. 

49. Quality By Design In Biomanufacturing 12/22/2011

    QbD is increasingly required in our industry, but there are still gaps in understanding how QbD applies to the biomanufacturing process.

50. Continuous Harvesting Of Extra-Cellular Proteins From Mammalian Cell Cultures Utilizing Small-Scale Perfusion 3/26/2012

    The use of a small-scale cell culture system not only maximizes the production of valuable protein but also avoids the high capital cost associated with system scale-up. Continuous harvesting can provide significant improvements in protein yields when compared to those of typical batch operations.
