ABSTRACT:
The present invention relates to a dry immunoassay analytical element for assaying a ligand, comprising a support bearing: (a) a label zone comprising an enzyme labeled ligand or an enzyme labeled receptor; (b) a spreading zone; (c) a receptor zone comprising a fixed concentration of an immobilized receptor for the ligand; and (d) a gravure zone comprising a diaryl telluride. A prefered embodiment of the present invention further comprises a vanadyl salt. The present invention further relates to a method for performing an assay using an element as described above.
