First, the high mortality induced by inoculation was independent of infection and time of inoculation of the beads.
An alternative explanation is the presence of leftover sediment inbetween the beads after the final wash step.
Although the new beads are always adjacent to already existing ones, connectivity is not explicitly imposed and this may result in unconnected models.
The molecule is tethered between two beads one held in the dual trap and the other a top a micropipette held by suction.
Restored linker conformations between the modules are displayed by a blue beads representation and varied from run to run.
Instead of mechanically deforming the beads, they allowed them to settle onto the glass, and to deform as the receptors and ligands bound.
The beads were then centrifuged for 2 minutes at 100xg and unbound material removed.
Separation over avidin beads isolated the cell-surface proteins that were accessible to the biotinylation reagent at the time of exposure.
