An electronic tag enclosure assembly includes an electronic tag and an enclosure having the electronic tag disposed therein. The resultant thinner portionin the prepreg layers with the respective thicker portions of metallization provide decoupling capacitors, while the resultant thicker portions, for example, provide a lower capacitance for improved trace impedance for the signal traces. The housing optionally forms a hook on the jet unit housing that is adapted to attach the jet unit to the inside surface of the liner when the jet unit is hooked onto the liner. The invention further relates to screening methods for identifying agonists and antagonists of full-length WF-HABP, WF-HABP, OE-HABP, and BM-HABP receptor activity.
