assessing S-levels in plants

Sorry to take up bandwidth.  This is for Jonathan who posted a response on 
this topic.  I got delete-happy and lost your e-mail.  The analysis of 
glutathione sounds ideal for this project.  If you have the time I would be 
interested in further details and advice on how to prep samples and carry out
the assay.  Thanks.
