Dynamic light scattering (DLS) studies revealed that compound 7 organizes itself as monodisperse aggregates in aqueous solution, nonetheless, as Hg2+ was added to the aqueous solution, disruption of aggregates was observed, resulting in a coordination complex under strong CHEQ (Chelation-Enhanced Fluorescent Quenching).
Our solution disruption experiments reinforce this view by showing that the Sm-B/B' subunits unfold more readily than any other subunit in the Sm ring, giving rise to an average of 23/24+ charges for the 26 kDa protein.
Interestingly, the first stable sub-complex in the assembly pathway of U1 snRNA: Sm-D1: Sm-D2: Sm-E: Sm-F: Sm-G is also a predominant species formed in our solution disruption experiments suggesting, as was observed recently for homomeric proteins, that the disassembly of protein complexes in solution often recapitulates their assembly pathway in vivo [48].
By contrast however charge states of the Sm-B/B', released in these solution disruption experiments (average 24/25+ for a 24 kDa protein) are greater than those observed following gas phase dissociation (cf ∼18+ for Sm-B/B', figure 1).
Solution disruption studies have successfully predicted the subcomplexes in several protein complex systems.
This result is also consistent with direct SID of the trimer formed by solution disruption.

Solution-phase organic solvent disruption coupled with native MS agrees with the previous SID results.
The results from both the previously reported SID experiments performed on a QTOF platform and the current solution-phase organic solvent disruption native MS experiments suggest that TNH is a dimer composed of αβγ trimers, and that α β interact strongly.
But the solution to disruption isn't to protect the past from the future or to freeze the old ways of doing things.
The most hazardous deterioration on the murals repaired by gelatin solution contains disruption, flaking and detachment.
The lowest particle size and PDI achieved after optimization of HSD speed and time indicated that sufficient dispersion energy was achieved and was well distributed within the solution for disruption of particle aggregates.

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
