Abstract: The present invention relates to solid supports for control nucleic acids. The present invention also relates to methods for the manufacture thereof, and methods of use thereof.
Abstract: Apparatus and washing and extracting head for an apparatus designed to wash microplates. The head is mobile above the microplate(s) in treating position and comprises an alignment of dispensing needles or tubes and suction needles or tubes associated in pairs, the number of the two types of needle pairs being equal to the number of wells per column or per row and the spacing between two adjacent pairs being equal to the spacing between two adjacent wells of the same column or row. The suction needles, and the parts of the consecutive suction and/or recovery circuit, have a passage cross sectional diameter not less than the largest transverse dimension of the sample supports present in the wells and the head comprises or co-operates with elements retaining the microplate to be washed or preventing it from being lifted, at least during the suction extraction phase.
Abstract: The invention proposes a liquid phase chromatography module (1) comprising: a container (2) having an upper end (4) and a lower end (5) which are open and have complementary shapes; a chromatographic mixture (9) in the container (2); a filtering membrane (10) fixedly disposed at one end (5) of the container (2). The invention also proposes a chromatography column comprising a stack of said modules (1) fitted together.
Abstract: The invention relates to a method of immobilizing an affinity reagent or affinity reagents on a hydrophobic solid phase which can be used in biological assays for analyte detection. The invention relates more particularly to a method of immobilizing an affinity reagent on a hydrophobic solid phase functionalized by a carboxyl group, said method comprising a step for activation of said solid phase and a step for coupling of the affinity reagent to said solid phase, characterized in that the step for activation of said solid phase uses a combination of a carbodiimide and a phosphate buffer in the presence of a co-activator and in an acid medium, and in that the coupling step is performed in a basic medium. The invention further relates to the reactive complexes obtained by this method and to their use in immunoassay kits, hybridization kits or enzymatic assay kits.
