The QuikPrep 96-well equilibrium dialysis plate from Harvard Apparatus, Holliston, Mass, is suited for high-throughput ligand-binding experiments, including protein-drug binding, protein-protein binding, protein-DNA binding, and serum protein binding assays. The patented design consists of two chambers separated by individual membranes, eliminating the possibility of cross contamination. Available in molecular weight cut-offs of 5kDa or 10kDa, the regenerated cellulose membrane allows for sample recovery. Designed for small volume samples, each chamber can hold 50–250 µL of sample or buffer. The standard plate footprint and well spacing meet the requirements for automation. The plate must be under 360° vertical rotation to achieve equilibrium. For more information, visit Harvard Apparatus.
