Abstract: A guiding device for coil nailers includes a nose connected to a barrel with a longitudinal path defined in the barrel and an inlet is located at the mediate portion of the longitudinal path. A side plate extends from the barrel and a guiding slot is defined in the inside of the side plate. A hollow portion is defined in the inside of the lower end of the side plate and a cylinder is located on outside of the side plate. A stop plate extends from one side of the inlet of the barrel. The minimum distance from one side of the stop plate to the other side of the inlet is between two respective maximum diameters of the nail shank and the nail head. A rib extends from the inside of the stop plate and toward the axis of the path to maintain the nails to be straight.

Abstract: This invention relates to a kit and a system for performing an in-solution microarray assay, and a method of carrying out this assay. The kit includes a plate having a number of wells in which a plurality of magnetic beads are placed. These magnetic beads are coated with different probes, wherein beads placed in each individual well are coated with identical probes.
