CA 2307141

Apparatus for producing a plurality of arrays of reagent regions is disclosed. A dispensing assembly in the apparatus has a plurality of heads which are spaced for depositing reagents at selected positions in different array areas in a substrate. As the heads in the assembly are advanced along array area, the regions in a row in that array are successively filled, allowing parallel deposition in several array areas at reagent regions which are closely spaced relative to the spacing between deposition heads in the assembly. Also disclosed is a method for producing a plurality of arrays using the apparatus.

L'invention porte sur un appareil permettant de réaliser une pluralité de matrices de titrage de régions de réactifs. Le bloc de distribution de l'appareil comporte une pluralité de têtes espacées de façon à disposer les réactifs en des points sélectionnés de différentes matrices sur un substrat. Les régions d'une même rangée de cette matrice se remplissent les unes après les autres, au fur et à mesure que les têtes du bloc de distribution progressent, ce qui autorise le dépôt parallèle, en plusieurs zones de la matrice, au niveau des régions de réactifs dont l'espacement est inférieur à celui des têtes du bloc de distribution. L'invention concerne également un procédé de production d'une pluralité de matrices de titrage au moyen de l'appareil.
