Cascaded all-optical quantization employing step-size MMI and shape-optimized power splitter

Jijun He, Xiaowei Zhang, Jian Wu, Ye Tian

As a key unit of future high-throughput communications, optical analog to digital converter (OADC) with all-optical quantizer element that simultaneously possesses high resolution, large bandwidth and compact size is highly promising. A pending issue of co ...

TubeSpin bioreactor 50 for the high-density cultivation of Sf-9 insect cells in suspension

Florian Maria Wurm, David Hacker, Lucia Baldi Unser, Xiaowei Zhang, Qiuling Xie

Here we present the TubeSpin bioreactor 50 (TubeSpins) as a simple and disposable culture system for Sf-9 insect cells in suspension. Sf-9 cells had substantially better growth in TubeSpins than in spinner flasks. After inoculation with 106 cells/ml, maxim ...

Hyperosmolarity enhances transient recombinant protein yield in Chinese hamster ovary cells

Florian Maria Wurm, David Hacker, Lucia Baldi Unser, Xiaowei Zhang, Isabel Fernandez Garcia

The effect of hyperosmolarity on transient recombinant protein production in Chinese hamster ovary (CHO) cells was investigated. Addition of 90 mM NaCl to the production medium ProCHO5 increased the volumetric yield of recombinant antibody up to 4-fold rel ...

Innovative, Non-stirred Bioreactors in Scales from Milliliters up to 1000 Liters for Suspension Cultures of Cells using Disposable Bags and Containers – A Swiss Contribution

Florian Maria Wurm, David Hacker, Lucia Baldi Unser, Mathieu Benjamin Stettler, Stéphanie Tissot, Xiaowei Zhang, Gilles Broccard

Innovative mixing principles in bioreactors, for example using the rocking of a platform to induce a backwards and forwards 'wave' , or using orbital shaking to generate a 'wave' that runs round in a cylindrical container, have proved to be successful for ...

Schweizerische Chemische Gesellschaft2010

Driven by the commercial success of recombinant biopharmaceuticals, there is an increasing demand for novel, cost-effective mammalian cell culture bioreactor systems for the production of biologicals requiring mammalian protein processing. Recently, orbita ...
