I'm investigating curative effects of certain plant extracts on copper
intoxicated snail embryos. Results are great, but in order to establisch
wheater this is merely due to the copper chelating action of the extract
i am looking for a simple method to extract the copper chelating
substances from the extract. My idea is to lead the extract over a
column that will bind the copper binding substances and test the extract
for remaining activity. Does anyone have any suggestion what column to
use and where to get it? Thanx
