ABSTRACT:
An adjustable-height vertical gel slab electrophoresis apparatus comprises a vertically oriented gel slab arranged between upper and lower buffer solution reservoirs. A bifurcated removable lower tray contains both an upper buffer reservoir drain and lower buffer reservoir. A gel mold experiment can be assembled and disassembled with unusual ease with the aid of unique self-locking clamp assemblies. Modular units may be vertically stacked to construct a vertical electrophoresis apparatus of variable height. Separable but interlocking upper and lower portions of the adjustable-height apparatus may have inserted between them intermediate insert assemblies which effectively extend the vertical height of the apparatus, thus facilitating flexibility in performing electrophoresis runs of greatly varying physical length without the need to purchase entirely separate units of different heights. Various interlocking wobble or tilt in either vertical plane. Means for stabilizing the apparatus in a true vertical position are also provided.
