I am currently expressing proteins in S. cerevisiae, then making spheroplasts
in order to lyse the cells. To make the spheroplasts, I am using a
combination of Zymolase and cytohelicase. The cytohelicase is available from
Sigma, but is pretty expensive for the quantities used in each experiment.
Does anyone know of other sources for this enzyme? Thanks for your help.
