[RASMB] pH stability

[Yasuaki Hiromasa]

Dear RASMB members,
I am working with peptide/protein at basic condition. I want to 
characterize it at pH10-12 or 1-10 mM NaOH. Can I apply under these 
condition to Analytical ultracentrifuge?  Will these base conditions hurt 
the cell assembly?
We have aluminum and epon centerpieces. Windows are quartz and sapphire.
We want to do velocity and equilibrium experiments.
Has anybody experience at these conditions?

Sincerely,
Yasuaki HIromasa
