Characterization of Aptamer-Protein Complexes by X-ray Crystallography and Alternative Approaches [PDF]

, 2012
Aptamers are oligonucleotide ligands, either RNA or ssDNA, selected for high-affinity binding to molecular targets, such as small organic molecules, proteins or whole microorganisms.

Clinical applications of next‐generation sequencing‐based ctDNA analyses in breast cancer: defining treatment targets and dynamic changes during disease progression

Molecular Oncology, EarlyView.
Circulating tumor DNA (ctDNA) offers a possibility for different applications in early and late stage breast cancer management. In early breast cancer tumor informed approaches are increasingly used for detecting molecular residual disease (MRD) and early recurrence. In advanced stage, ctDNA provides a possibility for monitoring disease progression and

Artificial Metalloenzymes Based on the Biotin-Streptavidin Technology: Challenges and Opportunities.

Accounts of Chemical Research, 2016
The biotin-streptavidin technology offers an attractive means to engineer artificial metalloenzymes (ArMs). Initiated over 50 years ago by Bayer and Wilchek, the biotin-(strept)avidin techonology relies on the exquisite supramolecular affinity of either ...

Respiratory complex I‐mediated NAD+ regeneration regulates cancer cell proliferation through the transcriptional and translational control of p21Cip1 expression by SIRT3 and SIRT7

Molecular Oncology, EarlyView.
NAD+ regeneration by mitochondrial complex I NADH dehydrogenase is important for cancer cell proliferation. Specifically, NAD+ is necessary for the activities of NAD+‐dependent deacetylases SIRT3 and SIRT7, which suppress the expression of p21Cip1 cyclin‐dependent kinase inhibitor, an antiproliferative molecule, at the translational and transcriptional

The case for trypsin release of affinity-selected phages

BioTechniques, 2010
Libraries of phages displaying diverse peptides are typically surveyed by affinity selection, using immobilized biomolecules as selectors. After exposing the library to the selector and washing away unbound phages, the bound phages are enriched for ...

Field-effect sensors - from pH sensing to biosensing: sensitivity enhancement using streptavidin-biotin as a model system.

In Analysis, 2017
Field-Effect Transistor sensors (FET-sensors) have been receiving increasing attention for biomolecular sensing over the last two decades due to their potential for ultra-high sensitivity sensing, label-free operation, cost reduction and miniaturisation.

Analysis of comprehensive genomic profiling of solid tumors with a novel assay for broad analysis in clinical diagnostics

Molecular Oncology, EarlyView.
In molecular cancer diagnostics, comprehensive genomic profiling (CGP) is going to replace the small NGS panels since it provides all clinically relevant somatic variants as well as genomic biomarkers with clinical value. Here, we compared two CGP assays and demonstrate that the choice for diagnostic implementation will depend on the specific ...

Controlling Multivalent Binding through Surface Chemistry: Model Study on Streptavidin

Journal of the American Chemical Society, 2017
Although multivalent binding to surfaces is an important tool in nanotechnology, quantitative information about the residual valency and orientation of surface-bound molecules is missing. To address these questions, we study streptavidin (SAv) binding to

Characterization and crystallization of core streptavidin.

Journal of Biological Chemistry, 1987
We have characterized a streptavidin product that had been reduced to a minimal size that still retained full biotin-binding activity. This core streptavidin is proteolyzed at both ends at points that correspond closely with the termini of hen egg white avidin. Core streptavidin is more soluble than is the parent molecule. We have grown three different
