A method of determining the concentration of an antigen in a sample solution comprising (a) coating an antigen-protein conjugate onto a solid matrix, (b) conjugating an enzyme to an antibody specific for said antigen, (c) to a known quantity of a solution containing the antibody-enzyme conjugate of (b) adding a specified quantity of a sample containing an unknown amount of the antigen whose content is to be determined, (d) contacting the coated solid matrix of (a) with the solution (c) and incubate so as to effect binding between the antibody and antigen, some of the antigen being that from the sample and some being that on the solid matrix, (e) removing the solid matrix from the solution and washing, (f) immersing the solid matrix in a solution containing a known amount of an enzyme-substrate which is acted upon by the enzyme so as to effect reaction between the enzyme and enzyme-substrate to produce a product, and then separating the solid matrix form the solution of enzyme-substrate, and (g) then measuring the solid matrix and/or the solution of enzyme-substrate with a pre-established standard to indicate the amount of antigen which was in the sample added in (c).

A method of promoting the more rapid growth of an animal or plant, which comprises administering to said animal, to a food source for said animal, to a plant or to a plant habitat a growth-promoting effective amount of leupeptin. The leupeptin can be incorporated into an animal feed or supplement containing a food base. It apparently functions by inhibiting proteases which degrade proteins, and thus reduce the growth of the host.

The present invention describes an apparatus and method for conducting immunochemical reactions in a self-contained sealed unit that requires only the addition of an unknown sample and water. The apparatus comprises a test tube with at least three chambers each containing different chemicals, including a solid sphere, and separated from each other by a water-soluble barrier.
