High-Throughput Single-Molecule Transcription Assay [PDF]
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]
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.
