A method for immunoassay of a viral antigen is performed on a membrane precoated with an inert protein. Nonimmunological capture of antigen takes place by absorption onto the coated membrane. Captured antigen binds to a tracer which includes a label conjugated to a specific antibody, the inert protein concomitantly inhibiting nonspecific binding of tracer. The label may be an enzyme which converts a substrate to a detectable product or converts a blocked inhibitor to an inhibitor whereby a second enzyme is inhibited from converting a substrate to a product. The invention includes a kit of materials for performing an assay in accordance with the method of the invention.

Immunoassay on a preblocked solid surface

An inboard rudder 6 harbors within a bearing assembly 12 which passes vertically from a hull 10 of a boat 2 to a cockpit floor 8 of the boat 2 such that the inboard rudder 6 can be rotated around a vertical (z) axis 7 by a tiller 14 and raised or lowered by pulling or pushing on the top of rudder 6. Rudder 6 can be rotated about an axis (y) parallel to the width of the boat 2, in the fore and aft direction, by pulling or pushing on tiller 14 thereby altering a sweep angle 28 of the rudder (FIG. 3). Rudder 6 can be rotated about an axis (x) perpendicular to the length of the boat 2.
