ABSTRACT:
The technique of separating a tagged bound material from the same unbound material in immunoassay procedures is improved by utilizing a clathrate sorbent to carry out the separation. A clathrate sorbent, for example, comprises a mixture of hydrate zinc sulfate and sodium hydroxide which form an inclusion compound with charcoal powder. Charcoal powder has also been combined to form a clathrate sorbent with salts of other metals which produce a gelatinous substance with alkaline hydroxides; e.g., alum with sodium hydroxide. Another example of a clathrate sorbent is magnesium trisilicate combined with the aforementioned zinc preparation.
