Electrophoretic member, electrophoretic device, electrophoretic method and sample dispensing probe

摘要

An electrophoretic member is structured such that a plate member as a base plate is provided with a separating flow path in a shape of a groove, and another plate member is provided with through-holes as small reservoirs at positions corresponding to both ends of the flow path. Both plate members are bonded together, so that the flow path is disposed inside thereof and both ends of the flow path communicate with the reservoirs to constitute an integrated base plate. Larger reservoirs having a size greater than that of the small reservoirs are connected at the positions of the small reservoirs on the plate member. Thus, a sample injection quantity can be minimized.
