Abstract: The presently disclosed subject matter provides compositions and methods comprising isolated antibodies that can recognize human prostate-specific membrane antigen (PSMA). The presently disclosed antibodies can be used to for imaging and therapy of PSMA-expressing cancers, such as prostate cancer, in a subject.

Abstract: A method for monitoring precipitation of a wax component in a hydrocarbon fluid stream i) using a labelled wax introduced in a fluid transport system at one in-flow point and measuring its absolute or relative concentration at one out-flow point is provided. A method for generating a labelled wax, and the use of a labelled wax is also provided.

Abstract: The present invention provides a method for monitoring precipitation of at least one wax component from a hydrocarbon-containing fluid stream during the flow of said fluid stream through a fluid transport system having at least one in-flow point and at least one out-flow point. The method comprises: i) introducing at least one labelled wax into said hydrocarbon-containing fluid stream at at least one in-flow point; and ii) measuring the relative or absolute concentration of said labelled wax in at least one sample taken at at least one out-flow point. The method may comprise sampling and analysing wax components from the hydrocarbon-containing fluid, identifying suitable wax components and generating labelled waxed based upon such components. Methods of generating labelled waxes and their uses are provided, along with corresponding methods for asphaltenes.

Abstract: The present invention relates to a method of adding nucleation seeds in order to promote the formation of hydrate particles in a flow containing hydrocarbon fluids and water. The method may include adding nucleation seeds at a point in the flow before the hydrate-forming area, the nucleation seeds being available for the promotion of the hydrate formation when this area is reached. The invention also relates to use of various compounds for the promotion of hydrate formation in such a fluid flow, thereby forming a transportable hydrate slurry.
