Abstract: There is described a system for multiparameter analysis of analytes. The system comprises: 1) primary supports (1) with a largest dimension (3) of 500 ?m or less suspended in use in a fluid solution; 2) each primary support (1) comprises an identification means (2) for identification thereof; 3) at least one primary analyte (12) is bound to each primary support (1); 4) a secondary analyte (12?) is suspended in use in the fluid solution; and 5) a measuring means (25) is arranged in communication with the fluid solution for monitoring interaction between the primary analyte (12) and secondary analyte (12?).

Abstract: The invention provides an analysis system for capturing target molecules in a sample. The system comprises: (a) supports with a largest dimension of 500 ?m or less, wherein each support includes at least one capture analyte bound thereto, said at least one analyte being at least one capture agent exhibiting an affinity for one or more of proteins, antibodies, antibody fragments, DNA aptamers, nucleic acids, small molecules and any other molecules used to bind target molecules; and (b) an arrangement for introducing said sample into contact with said at least one analyte of at least one support in a fluid solution, such that binding of at least one target molecule with at least one analyte is indicative of the presence of said at least one target molecule.

Abstract: In a method of making a cross-linked extruded product from polyethylene or other suitable polymer, the polymer is metered into a screw extrusion machine together with compounding ingredients comprising a hydrolysable unsaturated silane, a free-radical generator and a silanol condensation catalyst. The compounding ingredients are blended with the polymer in the barrel of the extruder and the mixture is heated sufficiently to effect grafting of silane groups to the polymer, the amount of free-radical generator being sufficiently low to limit direct free-radical cross-linking to a level that will not prevent extrusion of the material. The reaction mixture is extruded directly from the same extruder through an extrusion die to form an elongate shaped product and cross-linking is effected by subjecting the shaped product to the action of moisture.
