The method is non-destructive, allowing for measurements on the same plug without the need for fixation, dehydration, sectioning and decalcification.
A commonly cited disadvantage of the posterior approach is the need for fixation removal because of soft-tissue irritation over the prominent screw head [5, 18].
It was essential, that all markers were expressed on the surface of cells since we wanted to isolate living cells without the need for fixation and permeabilization.
Here, we employed atomic force microscopy (AFM) to more thoroughly characterize native exosomes without the need for fixation, staining, or labeling of these particles.
Consistent with expectations, the percentage of genes needed for fixation was low for nodes with high support from ML bootstrapping or from Bayesian posterior probabilities.
This effect allows selection for intermediates of complex traits, opening up a more direct route to the trait and thus reducing the time needed for fixation in the population.
A clear advantage of the FAP system is that unbound dye remains nonfluorescent in solution, allowing for the simple addition of dyes to the cellular media without any need for fixation or washout, and enabling live-cell imaging.
Other research [ 11] suggests that SCF requires less fusion interface than ACDF and shorter strut grafts, and for these reasons it may provide better stability without the need for fixation through a posterior approach.
Because sexual selection by female choice reduces the amount of time needed for fixation of male phenotypic characters, without reducing the effective population size of neutral mitochondrial genes, Masta and Maddison's method tests statistically whether the rate of fixation of mitochondrial sequences differ from those of male phenotypic characters.
The preference for a specific technique depends on the target animal species or carcass, combined with technical and practical aspects such as accuracy, reliability, cost, portability, speed, ease of use, safety and for in vivo measurements the need for fixation or sedation.
