Abstract: Apparatus and method for the separation of immiscible liquids are provided, and comprise the use of separator means having a surface which is preferentially "wettable" by one of the liquids to the substantial exclusion of another of the liquids. In use, the liquids are flowed from a common liquid source onto said surface with the one liquid being sorbed thereby to the substantial exclusion of the other liquid to thus substantially separate the liquids. The separator means surface may be maintained essentially level to retain the substantially separated liquid thereon, or may be inclined to result in the flow of the same therefrom under the influence of the force of gravity. Alternatively, the separator means may be made of a liquid-permeable material to permit the flow of the substantially separated liquid therethrough and therefrom under the influence of the force of gravity.

Abstract: A method for eliminating turbidity in a biological fluid by combining said fluid with a surfactant and an enzyme is disclosed as well as a diagnostic reagent formulation for that purpose.

Abstract: Disclosed is a specific binding assay composition and method for determining a ligand in a sample. The composition comprises (a) a binding partner for the ligand; (b) a detection system which has at least two components; (c) a selectively accessible vesicle having a surface-incorporated ligand or ligand analog and a first component of the detection system therein; (d) a substance which modifies vesicle accessibility in response to binding of surface-incorporated ligand or ligand analog and the binding partner; (e) at least one additional component of the detection system which is reactive with the first component to produce a detectable response; and (f) at least one surfactant which does not modify vesicle accessibility. The composition and method are suitable for use with automated, including continuous flow-type, analyzers.
