Site-Specific Protein Conjugation onto Fluorescent Single-Walled Carbon Nanotubes

Ardemis Anoush Boghossian, Vitalijs Zubkovs, Shang-Jung Wu, Nils Schürgers

Semiconducting single-walled carbon nanotubes (SWCNTs) are among the few photostable optical emitters that are ideal for sensing, imaging, drug delivery, and monitoring of protein activity. These applications often require strategies for immobilizing prote ...

Overexpression of transcription factor Foxa1 and target genes remediate therapeutic protein production bottlenecks in Chinese hamster ovary cells

Nicolas Mermod, Audrey Véronique Berger

Despite extensive research conducted to increase protein production from Chinese hamster ovary (CHO) cells, cellular bottlenecks often remain, hindering high yields. In this study, a transcriptomic analysis led to the identification of 32 genes that are co ...

Genetically encoded betaxanthin-based small-molecular fluorescent reporter for mammalian cells

Karl Gademann, Leo Scheller

We designed and engineered a dye production cassette encoding a heterologous pathway, including human tyrosine hydroxylase and Amanita muscaria 4,5-DOPA dioxygenase, for the biosynthesis of the betaxanthin family of plant and fungal pigments in mammalian c ...

Establishing a Ternary System for Optical Monitoring of DNA-Protein Interactions with Single-Walled Carbon Nanotubes

Shang-Jung Wu

DNA-protein interactions lie at the crux of life's essential processes. As such, various technologies have been developed to characterize these interactions. The distinct advantages of these technologies can be leveraged to study different facets of these ...

Allosteric Protein Switches based on Antibody Mimetics

Helen Rebecca Ostlund Farrants

Synthetic protein switches are proteins that can be controlled by an external input, and are useful tools to probe protein function. Antibody fragments and antibody mimetics can be selected to bind, activate, or inhibit several diverse protein targets. Nev ...

Scalable Production of AAV Vectors in Orbitally Shaken HEK293 Cells

Florian Maria Wurm, Bernard Schneider, Nicole Déglon, Vivianne Padrun

Adeno-associated virus (AAV) vectors are currently among the most commonly applied for in vivo gene therapy approaches. The evaluation of vectors during clinical development requires the production of considerable amounts of highly pure and potent vectors. ...

Expanding beyond the natural protein repertoire to engineer targeted vaccines and diagnostics

Fabian Sesterhenn

Proteins have evolved over millions of years to carry out the vast majority of biological functions that are fundamental to life. Their three-dimensional structures and functions have been in the focus of biomedical research for many decades, and substanti ...

Development of microfluidic tools and methods for the biochemical characterization of scFv and Cas9 affinity reagents and their applications in molecular detection

Ekaterina Emilova Petrova

Recent progress in protein engineering, empowered by the rapidly evolving fields of synthetic biology and DNA synthesis, has enabled the generation of various custom-designed proteins. Their thorough analysis has led to applications in areas including medi ...

Quantitative analysis of gene expression and transcriptional memory in mouse embryonic stem cells

Aleksandra Mandic

Quantitative studies of gene expression in have shown widespread variability in transcript and protein product abundance at the single-cell level. Such fluctuations in gene expression have been shown to lead to heterogeneous cellular responses and phenotyp ...

Dual-controlled optogenetic system for the rapid down-regulation of protein levels in mammalian cells

Patrick Andreas Gonschorek

Optogenetic switches are emerging molecular tools for studying cellular processes as they offer higher spatiotemporal and quantitative precision than classical, chemical-based switches. Light-controllable gene expression systems designed to upregulate prot ...

Cytosolic delivery and characterization of monobodies interfering with SH2 domain-phosphotyrosine interactions

Nadine Eliane Schmit

Targeted cancer therapy is a very promising concept; however, small molecule inhibitors only exist for a limited number of oncoproteins and resistance development limits their clinical use. Different engineered non-antibody scaffolds are being explored to ...
