ABSTRACT:
A blot screening apparatus is formed of a plate having numerous, elongated, narrow, shallow, parallel, separated reaction channels formed in one surface. The channel openings are positioned over a treated membrane which reacts with fluids introduced into the various channels. An elongated, narrow, groove-like socket, formed in the opposite plate surface, overlaps and extends transversely over each of the opposite and portions of the channels. Holes formed in the plate communicate the opposite ends of each channel with the base of its overlapping socket so that fluid samples may be separately introduced into each channel through its holes. Manifold plugs that are shaped to closely fit within the sockets are removably positioned in, and frictionally sealed against, the walls of the sockets, but are spaced from their adjacent socket bases. Each plug has a fluid flow passage for flowing a fluid simultaneously through the manifold plug to its socket base, through all of the base holes and channels, and out of the opposite channel holes, socket base and plug for simultaneously filling and draining all of the channels.
