Biomimetic PEG hydrogels crosslinked with minimal plasmin-sensitive tri-amino acid peptides

Matthias Lütolf, Jeffrey Alan Hubbell, Simone Rizzi, Martin Ehrbar

Semi-synthetic, proteolytically degradable polymer hydrogels have proven effective as scaffolds to augment bone and skin regeneration in animals. However, high costs due to expensive peptide building blocks pose a significant hurdle towards broad clinical ...

Selective cross-linking of interacting proteins using self-labeling tags

Kai Johnsson, Grazvydas Lukinavicius, Kui Thong Tan

We have designed molecules that permit the selective cross-linking (S-CROSS) of interacting proteins in cell lysates and the sensitive detection of the trapped complexes through in-gel fluorescence scanning. S-CROSS requires the expression of the putative ...

Micropatterning of Hydrogels by Soft Embossing

Matthias Lütolf, Thierry Laroche, Stefan Kobel, Samy Gobaa, Monika Limacher

Conventional in situ hydrogel micropatterning techniques work successfully for relatively stiff hydrogels, but they often result in locally damaged surfaces upon demolding in the case of soft and fragile polymer networks formed at low precursor concentrati ...

Conversion and shrinkage analysis of acrylated hyperbranched polymer nanocomposites

Yves Leterrier, Valérie Geiser

The photo-curing behavior of composites containing nanosized SiO2 in an acrylated hyperbranched polymer matrix was investigated by means of photo differential scanning calorimetry. The chemical conversion data were analyzed using an autocatalytic model, pa ...

Smooth muscle Notch1 mediates neointimal formation after vascular injury

Yiming Li, Freddy Radtke

Notch1 regulates binary cell fate determination and is critical for angiogenesis and cardiovascular development. However, the pathophysiological role of Notch1 in the postnatal period is not known. We hypothesize that Notch1 signaling in vascular smooth mu ...

A gel probe equilibrium sampler for measuring arsenic porewater profiles and sorption gradients in sediments: I. Laboratory development

Janet Gordon Hering

A gel probe equilibrium sampler has been developed to study arsenic (As) geochemistry and sorption behavior in sediment porewater. The gels consist of a hydrated polyacrylamide polymer, which has a 92% water content. Two types of gels were used in this stu ...

Of gels, offgel and off with the gel

Hoang-Trang Lam

In the context of prefractionation methods for proteomics, this work deals mainly with the development of electrophoretic tools for isoelectric focusing of peptides and proteins for the analysis of biological mixtures. In the light of existing devices for ...

Comprehensive proteome analysis of Mycobacterium ulcerans and quantitative comparison of mycolactone biosynthesis

Stewart Cole, Petra Tafelmeyer

Mycobacterium ulcerans is the causative agent of Buruli ulcer, a rapidly emerging human disease in which mycolactone, a cytotoxic and immunosuppressive macrocyclic polyketide, is responsible for massive skin destruction. The genome sequencing of M. ulceran ...

Synthesis of poly(PEGA) Bioconjugates using RAFT Polymerization

Emmanuelle Bays

Protein-polymer conjugates are widely used in biotechnology and medicine, and non-toxic polymers for bioconjugation would be advantageous for these applications. Herein, we reported the toxicity of polymers synthesized by two commonly employed controlled r ...
