<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Can anyone please point me to good references which discuss sedimentation equilibrium on weakly interacting (Kd > 10 uM) system of proteins (i.e, hetero-association)? I'm mostly interested in learning about the determination of MW and/or
stoichiometry of the fast-dissociating protein complexes and if it would be plausible using sedimentation equilibrium.
