tagetitoxin, a selective transcription of chloroplast

[diana]

Has anyone ever worked with tagetitoxin, a selective transcription 
inhibitor of chloroplast with arabidopsis?
I would like to know who sells tagetitoxin, and at which 
concentrations it is recommendable to
work with on Arabidopsis.
I would appriciate very much any info on this subject.
