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

Hybridoma tumor cell line A.T.C.C. No. HB8116. An anti-H-Y antigen monoclonal anti- body substance, Hyclonalan, produced by said cell line. Use of Hyclonalan in immunoselection methodology.

A method for removing a constituent such as immunoglobulins, lymphocytes, or immune complexes from a component of a patient's blood comprises the steps of: removing blood from the patient; separating the constituent con- taining component from the rest of the patient's blood; preparing an antibody; contacting th 9 constituent containing component with the anti- body so that the antibody may adsorb the con- stituent from the component; recombining the antibody contacted constituent containing com- ponent with the other components of the removed blood; and injecting the combined components of blood into the patient; wherein the adsorbing antibody is prepared by the steps of: removing selected cells from the constituent containing component of the patient's blood; in- jecting the removed cells into a non-human animal; allowing the non-human animal to manufacture antibodies to the injected cells; removing blood from the non-human animal; separating the same constituent containing com- ponent from the removed blood of the non- human animal; and removing the antibody from the constituent containing component of the non-human animal's blood. Another method for making the adsorbent antibody includes the steps of: creating cell cultures; cloning the anti- body producing cells; removing large quantities of the antibody; and purifying the antibody. General and specific apparatus for effecting the above methods are also disclosed.
