Single-Cell Droplet Microfluidic Screening for Antibodies Specifically Binding to Target Cells

Monoclonal antibodies are a main player in modern drug discovery. Many antibody screening formats exist, each with specific advantages and limitations. Nonetheless, it remains challenging to screen antibodies for the binding of cell-surface receptors (the ...

Determining the Surface Structure of Silicated Alumina Catalysts via Isotopic Enrichment and Dynamic Nuclear Polarization Surface-Enhanced NMR Spectroscopy

David Lyndon Emsley, Brennan James Walder, Jasmine Viger-Gravel

Isotopic enrichment of Si-29 and DNP-enhanced NMR spectroscopy are combined to determine the detailed surface structure of a silicated alumina catalyst. The significant sensitivity enhancement provided by DNP is vital to the acquisition of multinuclear and ...

Phenotypic Heterogeneity in Mycobacterium tuberculosis

John McKinney, Neeraj Dhar, Giulia Manina

The interaction between the host and the pathogen is extremely complex and is affected by anatomical, physiological, and immunological diversity in the microenvironments, leading to phenotypic diversity of the pathogen. Phenotypic heterogeneity, defined as ...

A single epidermal stem cell strategy for safe ex vivo gene therapy

Graham Knott, Jacques Rougemont, Yann Barrandon, Ariane Rochat, Andrea Zaffalon, Nicolas Grasset, Stéphanie Danièle Hélène Droz-Georget, Sara Benmohammed, Emmanuelle Savioz-Dayer, Alessandra Recchia

There is a widespread agreement from patient and professional organisations alike that the safety of stem cell therapeutics is of paramount importance, particularly for ex vivo autologous gene therapy. Yet current technology makes it difficult to thoroughl ...

Clonal, Self-Renewing and Differentiating Human and Porcine Urothelial Cells, a Novel Stem Cell Population

Yann Barrandon, Peter Frey, Jeffrey Alan Hubbell, Hans Mattias Larsson, François Gorostidi

Although urothelial progenitor-like cells have been described in the human urinary tract, the existence of stem cells remains to be proven. Using a culture system that favors clonogenic epithelial cell growth, we evaluated and characterized clonal human ur ...

CHO Quasispecies—Implications for Manufacturing Processes

Florian Maria Wurm

Chinese hamster ovary (CHO) cells are a source of multi-ton quantities of protein pharmaceuticals. They are, however, immortalized cells, characterized by a high degree of genetic and phenotypic diversity. As is known for any biological system, this divers ...

Mutation accumulation in space and the maintenance of sexual reproduction

Marcel Salathé

The maintenance of sexual reproduction remains one of the major puzzles of evolutionary biology, since, all else being equal, an asexual mutant should have a twofold fitness advantage over the sexual wildtype. Most theories suggest that sex helps either to ...

Sexual selection and its effect on the fixation of an asexual clone

Marcel Salathé

Sexual selection is a powerful and ubiquitous force in sexual populations. It has recently been argued that sexual selection can eliminate the twofold cost of sex even with low genomic mutation rates. By means of differential male mating success, deleterio ...

Fluorescent proteins in animal cells for process development: optimization of sodium butyrate treatment as an example

Florian Maria Wurm, Martin Jordan, Lisa Hunt

Fluorescent proteins expressed in mammalian cells can be quantified quickly and noninvasively with a standard fluorescence plate reader. We have previously exploited this quality in cell growth assessment (Hunt et al., 1999b). In this work, different CHO c ...

Development of stable cell lines for production or regulated expression using matrix attachment regions

Florian Maria Wurm

One of the major hurdles of isolating stable, inducible or constitutive high-level producer cell lines is the time-consuming selection procedure. Given the variation in the expression levels of the same construct in individual clones, hundreds of clones mu ...
