Re: your request for means to disassemble a virus of mushrooms that
will separate but not degrade the capsomeres.
It is possible with some plant viruses to nudge the capsomeres apart
without destroying them, using a combination of pH stress and solvent
polarity stress. J. S. Semancik and J. B. Bancroft published such a
method in 1965 (Stability differences between the nucleoprotein
components of bean pod mottle virus, Virology, Volume 27, pages
476-483). They exposed the virions to chloroform at pH between 9 and
10. I used their approach in my MS thesis research (1971) at the
University of Arkansas in Fayetteville (Effects of organic solvents and
alkalinity on components of two isolates of bean pod mottle virus).
