New study highlights interconvertible RecA–ssDNA states with the help of u-Flux™ microfluidics

A recent publication in FEBS Letters describes how the presence of ADP and ATP affects the structural transitions that single-stranded DNA (ssDNA) undergoes upon RecA-filament assembly. The researchers used the u-Flux™ Laminar Flow Microfluidics combined with optical tweezers to demonstrate that the bacterial homologous recombination-enzyme exists in two interconvertible states.…

Investigation of the Interaction of RAD51 with ssDNA Using CTFM and X-ray Crystallography

Recently, the paper “Two distinct conformational states define the interaction of human RAD51-ATP with single-stranded DNA" has been published in The EMBO Journal. Congratulations to Dr. Ineke Brouwer and all co-authors! Brouwer et al. combined Correlative Optical Tweezers-Fluorescence Microscopy (CTFM) with X-ray crystallography to investigate the function of human RAD51…

Strand-Displacement Polymerization by Reverse Transcriptase Investigated using LUMICKS’ u-Flux™

The journal Nucleic Acids Research has recently published the paper "Pausing kinetics dominates strand-displacement polymerization by reverse transcriptase". We would like to congratulate the authors! Malik et al. (2017) used optical tweezers and, among other technologies, microfluidics to study the enzymatic activity of the murine leukemia Virus reverse transcriptase (RT). RT catalyzes the formation of an integration-competent double-stranded DNA…
