My supervisor has been told about a method to stain myelin using colloidal
gold and want's to try it.  The person who told her about the method
refered to the Cajal method.  I've looked through the literature and cannot
seem to find any reference to colloidal gold and myelin staining.  Is she
thinking of a method that:

a) uses colloidal gold conjugated to either a primary or secondary antibody
i.e. tracers for EM; or

b) a method that uses gold chloride.

Any assistance will be greatly appreciated.

Thank You in advance,
