I think the affinity of streptavidin for biotin is so strong that the
binding is more or less irreversible. I hope I'm wrong. I've always found
Vector Labs who specialise in avidin/biotin to be extremely helpful. I don't
know if they are in Australia but here's there US No. (415) 697 3600 
Fax (415) 697 0339. It says here on their data sheet that avidin has a binding
affinity of 10e-15M for biotin!
