DOWNSTREAM PROCESSING WHITE PAPERS & CASE STUDIES

• Biomanufacturing Complexity

  This white paper addresses one of the most serious challenges facing biomanufacturing professionals today - how to understand and then deal with the extreme complexity associated with biotechnology manufacturing.

• 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.
• Guidelines For Proper Filtration And Delivery Of Samples To On-Line Process Analyzers

  Increasingly precise process control strategies, often linked to computer control, have accelerated the use of sophisticated on-line chemical composition analyzers in plant applications. Instruments such as gas and liquid chromatographs, ion chromatographs, laser optic instruments, atomic absorption instruments and specific ion analyzers, which were rarities in laboratories ten years ago, are now found routinely in plant settings.

• Examining Column Reproducibility During Method Development In Clinical Labs

  In this study demonstrates how the HSS T3 stationary phase is a reliable stationary phase, as three batches made over a five-year span provide comparable results.

• Cultivation Of Human CAP Cells: Evaluation Of Scale-Down Capabilities

  The following application note illustrates how the DASbox Mini Bioreactor System combined with the BioBLU 0.3c single-use vessels supports bioprocess development in human 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.
