Abstract: There is provided a radiolabeled monoclonal antibody of the class IgG.sub.1 which reacts readily with both normal human and dog blood platelets while failing to react with thrombasthenic human platelets. This antibody has the property of completely blocking interaction of fibrinogen with platelets induced by ADP, and the ability to detect fresh thrombi in vivo.

Abstract: Polyarylalkane oligomer compositions consisting essentially of a mixture of isomers of xylyl-xylene and of higher homologues and a mixture of isomers of bis(dimethylphenyl)xylylene and of higher homologues; the method of making such compositions by first reacting toluene, xylene, or a mixture of toluene and xylene with chlorine in the presence of a radical generator, removing the unreacted toluene, and then subjecting the reaction product to the action of an inorganic halide or inorganic acid in the presence of xylene, and microcapsules containing color-forming material wherein the compositions are used as solvents for the color-forming material.
Abstract: A process for recrystallizing crude, rod-like or jagged crystals of 3-nit1,2,4-triazol-5-one into spheroidal crystals by using water containing from 0.01 to 0.20 weight percent of a fluorochemical surfactant and from 0.01 to 0.20 weight percent of methyl cellulose.
