High-Throughput Single-Molecule Transcription Assay [PDF]
Biophysical Journal, 2012 The study of the role and mechanics of proteins in a cell is crucial to understanding the complexity of cells. Most biological systems respond to a change by adding heterogeneity to its population states. One of the most effective ways of studying a biological system is to compare the population states of proteins as a function of time and chemical ...

DNA Y Structure: A Versatile, Multidimensional Single Molecule Assay [PDF]
Nano Letters, 2014 Optical trapping is a powerful single molecule technique used to study dynamic biomolecular events, especially those involving DNA and DNA-binding proteins. Current implementations usually involve only one of stretching, unzipping, or twisting DNA along one dimension.

A functional single-molecule binding assay via force spectroscopy [PDF]
Proceedings of the National Academy of Sciences, 2007 Protein–ligand interactions, including protein–protein interactions, are ubiquitously essential in biological processes and also have important applications in biotechnology. A wide range of methodologies have been developed for quantitative analysis of protein–ligand interactions.

Visualizing helicases unwinding DNA at the single molecule level. [PDF]
, 2010 DNA helicases are motor proteins that catalyze the unwinding of double-stranded DNA into single-stranded DNA using the free energy from ATP hydrolysis. Single molecule approaches enable us to address detailed mechanistic questions about how such enzymes ...
