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.
