Help: looking for a source for phytochelatin.

I am looking for a  source for phytochelatin (PC)  or cadystin (a metal  
binding peptide), the molecular composition of which is   (r-GluCys)n-Gly 
(generally n=2-11, but I'd  like to have n=2-4).

I am a graduate student of Dept. of Biology of Seoul Natl. Univ. in Korea.
To investigate  the  induction profiles   of the PC   by the  heavy metal   
stresses and the compositions of PCs  with different values  of n,  I  am 
trying to  separate Cd-PC  complex through Sephadex G-50 gel  column.  In this 
experiment,  I need standard chemicals  for PC with n = 2-4,  because PCs with 
n=2-4 is reported to be normally found in plants.
Unfortunately, I do not have any idea where can I get it or whom do I have to 

Please help me and I will greatly appreciate.
