Abstract

The invention concerns a mask for distributing reagents on an analytical support, such as an electrophoresis gel, the mask having a body with parallel upper and lower surfaces, a plurality of lanes located on the lower surface of the mask have wedge-shaped projecting elements with a sloped surface between first and second ends thereof, an opening extends from the upper surface of the body of the mask to the lowest point of the sloped surface. The mask is positioned over an analytical support and loaded with the desired reagents which are held by capillary action between the mask and the analytical support. The mask can then be moved in a sweeping motion across the analytical support to deposit the reagents thereon. In another embodiment, the projecting elements are rectangular in shape and the mask is positioned at an incline with respect the analytical support.
