Antigenic substances having amino and/or carboxyl groups are bound covalently, with preservation of their electrochemical state, that is with preservation of the amino and/or carboxyl groups, to a particulate carrier which is not decomposable in the body of a vertebrate; such substances are introduced as an antigen into the body of a vertegrate to provoke an immune response of high specificity and long duration.

Method for inducing antibody formation

Synthetic stool, adaptable to use as a control standard in the diagnostic detection of substances contained in stools and for demonstration purposes, said stool comprising a matrix of a member selected from the group consisting of oxygen-containing organic polymers which are difficultly soluble in water and oxygen-containing inorganic solids difficultly soluble in water, a non-bleeding coloring agent adherent to said matrix and simulating the color of a stool, and a liquid selected from the group consisting of water and lubricants.

Synthetic stool

The invention relates to diagnostic agents for the rapid diagnostic detection of blood in excretions and body fluids, consisting essentially of a solid support which is charged with a chromogenic substance as indicator and impregnated with an acrylic and/or methacrylic resin.

Rapid diagnostic agents

Packaged diagnostic test strip comprising a first or front sheet having at least one aperture therein, said aperture or apertures having at least one included angle equal to or less than 90 degrees; a diagnostic test strip under said front sheet and extending under said aperture or apertures, said test strip carrying a diagnostic reagent; a second or back sheet supporting said test strip in layered arrangement therewith and with said front sheet, said back sheet having at least one flap-covered aperture therein in that region thereof corresponding with the location of said aperture or apertures in said front sheet, whereby when the flap is open said test strip is exposed thereunder; and a closure flap at least partially extending over said front sheet and having closure means thereon for covering said aperture or apertures in said front sheet when in closed position.
