Abstract:
An apparatus for producing an array of liquid-reagent spots on a substrate, comprising:a manifold having a plurality of capillary channels, each adapted to hold a selected liquid, said channels having opposite upper-end and lower-end openings, and inner diameters which decrease on progressing from the upper- to the lower-end openings, with said lower openings forming said array, a support movable between raised and lowered positions with respect to said manifold, and a plurality of fibers carried on said support for movement therewith, each fiber being adapted to move longitudinally within an associated channel, as the support is moved between its raised and lowered positions, with movement of the fibers from their raised to lowered positions being effective to deposit a selected volume of liquid from each channel in the manifold.
