8M urea and 6M Gu-HCl: can they lysis yeast cell wall

[clarosa]

Think about an additional  mechanical means to disrupt such as a bead
beater, sonication,  pressure disruption.  I do not believe those agents
break the cell wall.  Surely there are well worked out protocols for yeast
protein extraction.
