In response to specific stimuli, keap1 dissociates; then Nrf2 translocates into the nucleus and activates its target genes [ 15].
This suggests that a single PcrA, once recruited by RepD to the dso, largely remains bound until the plasmid is fully unwound, although we cannot completely exclude the possibility of PcrA dissociating then rapidly rebinding prior to any reannealing.
Following the initial increase in fluorescence intensity, there is a slower further increase due to PcrA dissociating, then binding and unwinding other RepD-DNA complexes in a steady state.
Antibodies of the human IgG4 subclass uniquely undergo a process of Fab-arm exchange in which the heavy-chains of antibodies of different specificities can dissociate and then recombine.
We believe that the biphenyl linker in the HB-FePc catalyst may connect phthalonitrile fragments decomposed from FePc, while the residual iron atoms dissociate and then generate clusters, which are easily oxidized in air to form iron oxides.
This implies that there is a reversal in the (de)aggregation mechanism at some point during the lowering of the pH first the aggregates dissociate, and then the process reverses direction and they precipitate.
Likewise, in vivo, telomerase can dissociate and then reassociate with a given telomere in a single cell cycle (Chang et al. 2007).
These single-atom Pd sites lower the energy barrier to hydrogen uptake, allowing it to dissociate and then spill over onto the bare Cu terraces.
Briefly, secondary lymphoid organs were mechanically dissociated and then filtered through a 100 µ nylon cell strainer (BD Labware, Mountain View, CA) to exclude undissociated fragments.
Human embryonic stem cells were passaged by incubation in 1 mg/ml collagenase IV (animal-free, Invitrogen) for 5 8 minutes at 37°C or mechanically dissociated and then removed to freshly prepared human foreskin fibroblast layer.
