The ability to perform well-controlled investigations early in the process of fiber formation, which vary single input parameters (i.e. collagen concentration, crowding agent concentration, draw rate, flow rate, temperature, pH, etc).
Because these accessible H2A nucleosomes still extend to as wide as 170±54 bp, at practical MNase concentrations, crowding with histones or other DNA-bound proteins are not likely to have major effects for extended peaks.
At higher concentrations of crowding agents, these effects were less pronounced, supporting the notion that higher viscosity slows down diffusion-controlled additions of monomers to preexisting oligomers and proto-fibrils.
These differences can be exaggerated by modifying the solution concentration, molecular crowding, agitation, temperature, pH and ionic strength [ 53].
Binding to ligands (allosteric regulators), or simply protein concentration, or crowding, may switch stabilities among conformations and trigger the shape transition.
Experimental aggregation conditions such as initial concentration, molecular crowding, temperature, pH, ionic strength, agitation, phosphorylation, and polyion presence can determine both aggregation kinetics (accelerating or inhibiting the fibrillation) and structural properties [ 11– 11].
Regarding the effect of stress, the main effect of crowding on pCort concentration was significant, but the most pronounced increase was observed in BHR, suggesting that young females of this genotype are particularly sensitive to this stressor.
Elevated macrophage infiltration led to high levels of crowding effect and high concentrations of MMP-9 for collagen degradation.
The extent to which microviscosity is experienced by a particle depends on its radius, and the crowding agents' dimensions and concentrations.
The term "concentration" can only be used synonymously with crowding level when one size of crowder is present, whereas crowding level can be used for any type of crowding, including mixtures of multiple sizes or even multiple types of crowders.
Molecular crowding agents increase the apparent local concentration of components by excluding volume, shifting the equilibria of biomolecular interactions in favor of associated states.
