Crowding agent
WebSep 2, 2014 · Crowding agents PEG-8000, Ficoll-70 and Ficoll-400, when added to cell-free systems at certain concentrations, have been found to boost transcription but inhibit translation [30]. WebAddition of Tween or the crowding agents Ficoll and dextran, showed that neither surface adsorption, diffusion limitations nor simple volume crowding affected the aggregation rate. Fitting of kinetic data to a wide range of mechanistic models implied a reversible two-state conformational switch mechanism from aggregation-prone monomers ( N ...

WebJun 26, 2012 · In the presence of the crowding agent Ficoll we do not observe a change in k cat, 490±20 s −1 in comparison to the absence of the crowding agent (490±30 s −1). Similarly, there is an insignificant decrease in the K m value (2,000±300 µM) between the crowded and uncrowded conditions. Thus, the activity of PGK for 3-PGA as a substrate is ...
